Mix the・ingredients together in a heatproof bowl. De-vein and peel the shrimp, rinse quickly in water and pat dry with paper towels. Sprinkle with sake and salt and let rest, then dust with katakuriko (not listed).
Place the shrimp on top of the combined sauce ingredients. Cover loosely with plastic wrap, and microwave for 3 to 4 minutes at 500w. Even if the shrimp look transparent, they will continue to cook as you take the bowl out and mix with the sauce.
Line a plate with lettuce, plate the shrimp and sauce on top, and it's done!
Story Behind this Recipe
I first learned about sweet chili sauce on Cookpad. I wondered if this could make a quick shrimp in chili sauce. I found a bottle at the supermarket and tried it with roast chicken and pork. The label said it has chili peppers, sugar, vinegar, sesame, and lots of other spices. I looked through other Cookpad recipes that used the sauce, and combined it with microwave recipes by Harumi Kurihara (a TV cooking star and cookbook author) to make a super-fast shrimp with chili sauce.
This is even easier if you use peeled shrimp. The microwave cooking time varies depending on the size and amount of shrimp, so stop the microwave a little early and check.
