Steps

1. In a bowl, combine 1.5 tbsp Miso, 2 tsp Mayonnaise, 2 tsp Sugar, and 2 tsp Cooking Sake (Rice Wine). Whisk thoroughly to ensure no miso clumps remain. [Key Tip!] Adding mayonnaise adds richness and a smooth texture to the miso glaze, making it an excellent pairing with the chicken tenders.

2. Prepare a bowl and pat dry the surface of 6 Chicken Tenders (approx. 400g) with paper towels. [Key Tip!] Thoroughly drying the chicken tenders helps to reduce any gamey odor and allows the seasoning to penetrate better.
   🕒 01:19
3. Cut the chicken tenders straight in half lengthwise. Cut them to be equal halves, not along the tendon lines.
   🕒 02:00
4. For the cut chicken tenders, if there are any remaining stringy white parts (tendons), make a diagonal cut with a knife to remove them. [Key Tip!] You don't need to remove all the tendons; just removing these stringy parts will significantly reduce the chewy texture, resulting in a delicious and easy dish.

5. Place the cut chicken tenders into the prepared bowl.

6. Line a toaster oven baking tray with parchment paper or non-stick aluminum foil.
   🕒 02:49
7. To the bowl with the chicken tenders, add a pinch of Salt, 1 tbsp Cooking Sake (Rice Wine), 1 tbsp Mirin (Sweet Rice Wine), a pinch of MSG (Umami Seasoning), and 1 tsp Potato Starch.
   🕒 03:15
8. Once all seasonings are added, thoroughly knead them into the chicken tenders until no excess liquid remains. [Key Tip!] Kneading in the potato starch and liquids will lock moisture inside the chicken tenders, ensuring they remain juicy and don't dry out when grilled. This is a crucial step for retaining meat juices.
   🕒 03:38
9. Arrange the kneaded chicken tenders on the prepared baking tray, leaving a slight gap between each piece. [Key Tip!] Leaving space between the chicken tenders ensures even cooking and prevents uneven browning.
   🕒 04:18
10. Spread the prepared miso glaze over the surface of the chicken. [Key Tip!] Applying the glaze just before grilling, rather than marinating, clearly separates the chicken's flavor from the glaze's taste, allowing you to enjoy a more yakitori-like flavor.
    🕒 04:46
11. Grill in a 1000W toaster oven for about 6-7 minutes. [Key Tip!] Chicken tenders cook quickly due to their thinness, so after about 6 minutes, check for doneness and any signs of burning.
    🕒 05:18
12. Cut one of the largest chicken tenders in half to check if it's cooked through.
    🕒 05:52
13. Plate and serve. Enjoy!
