## Ingredients You’ll Need

### For the Tenderloin:

* **1.5 lbs Beef Tenderloin:** Look for a center-cut tenderloin, as it will be the most uniform in thickness and cook evenly. Make sure the tenderloin is properly trimmed of any silverskin.
* **1 tbsp Olive Oil:** Or any other neutral cooking oil with a high smoke point, such as canola or avocado oil. This is used for searing the tenderloin.
* **1 tsp Salt:** Preferably sea salt or kosher salt, to enhance the flavor of the beef.
* **1/2 tsp Black Pepper:** Freshly ground black pepper is always preferred for the best flavor.

### For the Thai Sauce:

* **2 tbsp Vegetable Oil:** Used for sautéing the aromatics.
* **2 cloves Garlic:** Minced finely. Garlic is a foundational flavor in Thai cuisine.
* **1 inch Ginger:** Peeled and minced finely. Ginger adds a warm, spicy, and slightly sweet note.
* **1 Red Chili:** Finely chopped (adjust to your spice preference). Bird’s eye chilies are commonly used in Thai cooking for their intense heat, but you can use a milder chili like a Fresno or Serrano if you prefer.
* **1/4 cup Soy Sauce:** Use low-sodium soy sauce to control the saltiness of the dish. Tamari can be used as a gluten-free alternative.
* **2 tbsp Fish Sauce:** A key ingredient in Thai cuisine, fish sauce adds a salty, umami flavor. Use a good quality fish sauce for the best results.
* **2 tbsp Brown Sugar:** Light or dark brown sugar can be used. Brown sugar adds sweetness and depth of flavor to the sauce.
* **2 tbsp Lime Juice:** Freshly squeezed lime juice adds acidity and brightens the flavors of the sauce.
* **1 tbsp Rice Vinegar:** Rice vinegar adds a mild, slightly sweet acidity to the sauce. You can substitute with white wine vinegar if necessary, but rice vinegar is preferred.
* **1 tbsp Cornstarch:** Used to thicken the sauce. Mix it with 2 tablespoons of cold water to create a slurry before adding it to the sauce.
* **2 tbsp Water:** For adjusting the consistency of the sauce.
* **2 tbsp Chopped Fresh Cilantro:** For garnish, adding a fresh, herbaceous note.
* **1 tbsp Chopped Green Onions:** For garnish, adding a mild oniony flavor and visual appeal.
* **1 tbsp Sesame Seeds (optional):** For garnish, adding a nutty flavor and visual appeal.

## Equipment You’ll Need

* **Cutting Board:** For preparing the ingredients.
* **Sharp Knife:** For trimming the tenderloin and chopping the vegetables.
* **Large Skillet or Wok:** A skillet or wok with high sides is ideal for searing the tenderloin and making the sauce.
* **Small Bowl:** For mixing the cornstarch slurry.
* **Measuring Spoons and Cups:** For accurate ingredient measurements.
* **Tongs:** For turning the tenderloin while searing.
* **Meat Thermometer (optional):** For ensuring the tenderloin is cooked to the desired doneness.

## Step-by-Step Instructions

### 1. Prepare the Tenderloin:

* **Trim the Tenderloin:** Use a sharp knife to remove any silverskin or excess fat from the beef tenderloin. This step is crucial for achieving a tender and even-cooking result. Silverskin is a tough membrane that doesn’t break down during cooking, so it’s important to remove it. To do this, slip the knife under the silverskin and gently slice it away from the meat. Be careful not to remove too much of the surrounding flesh.
* **Cut into Medallions:** Cut the tenderloin crosswise into medallions that are about 1.5 to 2 inches thick. This size is ideal for searing and ensures that the beef cooks quickly and evenly. Thicker medallions will take longer to cook and may not be as tender. You should get approximately 8-10 medallions from a 1.5-pound tenderloin.
* **Season the Medallions:** Season the medallions generously with salt and freshly ground black pepper on both sides. This is the only seasoning the beef will get directly, so don’t be shy. Make sure to coat each medallion evenly. The salt will help to draw out moisture from the beef, which will create a nice crust when searing. The pepper adds a subtle spice and enhances the overall flavor.
* **Let the Meat Rest:** Allow the seasoned medallions to sit at room temperature for about 15-20 minutes before searing. This allows the meat to relax and come closer to room temperature, which will result in more even cooking. If you sear the beef straight from the refrigerator, the outside will cook much faster than the inside, potentially resulting in a tough, unevenly cooked piece of meat.

### 2. Prepare the Thai Sauce:

* **Prepare the Aromatics:** Mince the garlic and ginger finely. Finely chop the red chili (remove the seeds if you prefer less heat). Having these ingredients prepped and ready to go will ensure a smooth and efficient cooking process.
* **Create the Cornstarch Slurry:** In a small bowl, whisk together the cornstarch and 2 tablespoons of cold water until smooth. This slurry will be used to thicken the sauce. Make sure there are no lumps in the slurry. Set aside.
* **Sauté the Aromatics:** Heat the vegetable oil in a large skillet or wok over medium heat. Once the oil is hot, add the minced garlic, ginger, and chopped red chili. Sauté for about 1-2 minutes, or until fragrant. Be careful not to burn the garlic, as it can become bitter.
* **Add the Sauce Ingredients:** Pour in the soy sauce, fish sauce, brown sugar, lime juice, and rice vinegar. Stir well to combine and dissolve the brown sugar. Bring the sauce to a simmer.
* **Thicken the Sauce:** Slowly pour the cornstarch slurry into the simmering sauce, stirring constantly. Continue to stir until the sauce thickens to your desired consistency. This should take about 1-2 minutes. If the sauce becomes too thick, add a tablespoon or two of water to thin it out.
* **Taste and Adjust:** Taste the sauce and adjust the seasonings as needed. You may want to add more lime juice for acidity, brown sugar for sweetness, or fish sauce for saltiness. Keep in mind that the sauce will intensify in flavor as it reduces, so don’t over-season it.
* **Keep Warm:** Once the sauce is thickened and seasoned to your liking, remove it from the heat and keep it warm while you sear the tenderloin. You can cover the skillet with a lid or transfer the sauce to a separate container to prevent it from reducing further.

### 3. Sear the Tenderloin:

* **Heat the Oil:** Heat the olive oil in a large skillet or wok over high heat. Make sure the skillet is very hot before adding the tenderloin medallions. A hot skillet is essential for achieving a good sear and preventing the beef from sticking.
* **Sear the Medallions:** Working in batches (do not overcrowd the pan), carefully place the tenderloin medallions in the hot skillet. Sear for about 2-3 minutes per side for medium-rare, or longer for your desired doneness. Use tongs to turn the medallions. The goal is to achieve a nicely browned crust on the outside while keeping the inside pink and juicy. Overcrowding the pan will lower the temperature and prevent the beef from searing properly.
* **Check the Internal Temperature (Optional):** For precise cooking, use a meat thermometer to check the internal temperature of the tenderloin. For medium-rare, the internal temperature should be 130-135°F (54-57°C). For medium, it should be 135-145°F (57-63°C). For medium-well, it should be 145-155°F (63-68°C). And for well-done, it should be 155°F (68°C) and above. Keep in mind that the internal temperature will continue to rise slightly after you remove the meat from the heat, so it’s best to take it off the heat a few degrees before it reaches your desired doneness.
* **Rest the Meat:** Once the tenderloin medallions are seared to your liking, remove them from the skillet and place them on a cutting board. Let the meat rest for about 5-10 minutes before slicing. This allows the juices to redistribute throughout the meat, resulting in a more tender and flavorful final product. If you slice the meat immediately after searing, the juices will run out, and the meat will be drier.

### 4. Assemble and Serve:

* **Slice the Medallions (Optional):** If desired, slice the tenderloin medallions thinly against the grain. This will make them even more tender and easier to eat. Slicing the meat against the grain shortens the muscle fibers, making it more tender.
* **Serve with the Sauce:** Arrange the seared tenderloin medallions (or slices) on a serving platter or individual plates. Generously spoon the warm Thai sauce over the beef.
* **Garnish:** Garnish with chopped fresh cilantro, chopped green onions, and sesame seeds (if using). These garnishes add a fresh, vibrant flavor and visual appeal to the dish.
* **Serve Immediately:** Serve the Thai Quivering Tenderloins immediately while they are still warm and the sauce is glossy and flavorful. This dish is best enjoyed fresh.

## Tips for Success

* **Choose the Right Cut of Beef:** Using beef tenderloin is essential for achieving the signature tenderness of this dish. Don’t substitute with other cuts of beef, as they will not be as tender.
* **Trim the Tenderloin Properly:** Removing the silverskin is crucial for achieving a tender result. Take your time and carefully remove all of the silverskin before searing the beef.
* **Don’t Overcook the Beef:** Beef tenderloin is best served medium-rare to medium. Overcooking will result in a tough and dry piece of meat. Use a meat thermometer to ensure precise cooking.
* **Use High Heat for Searing:** Searing the tenderloin over high heat is essential for achieving a good crust and preventing the beef from sticking to the pan. Make sure the skillet is very hot before adding the beef.
* **Don’t Overcrowd the Pan:** Sear the tenderloin in batches to avoid overcrowding the pan. Overcrowding will lower the temperature and prevent the beef from searing properly.
* **Rest the Meat Before Slicing:** Letting the meat rest before slicing allows the juices to redistribute throughout the meat, resulting in a more tender and flavorful final product.
* **Use Fresh Ingredients:** Using fresh ingredients, especially the garlic, ginger, chili, and lime juice, will result in the best flavor in the Thai sauce.
* **Adjust the Spice Level to Your Preference:** The amount of chili in the recipe can be adjusted to your preferred spice level. If you like it mild, use less chili or remove the seeds. If you like it hot, use more chili or add a pinch of chili flakes.
* **Taste and Adjust the Sauce:** Taste the sauce and adjust the seasonings as needed. You may want to add more lime juice for acidity, brown sugar for sweetness, or fish sauce for saltiness.
* **Serve Immediately:** Serve the Thai Quivering Tenderloins immediately while they are still warm and the sauce is glossy and flavorful.
