Hot and Sour Stir-Fried Squid

Method

1. 1 Score the inside of the squid with dragon scale-like cuts, then cut into pieces and pat dry thoroughly.
2. 2 Prepare the sauce beforehand by mixing vinegar, sugar, fish sauce, chopped chili peppers, and cornstarch dissolved in water.
3. 3 Sauté the squid over the highest heat for exactly 60 seconds, then remove it immediately.
4. 4 Sauté the onions, bell peppers, tomatoes, and pineapple for 2 minutes until the vegetables are still crisp.
5. 5 Pour in the prepared sauce and simmer for 40 seconds until the sauce thickens.
6. 6 Return the squid to the pan and toss for 20 seconds; the total time the squid is cooked over low heat is 90 seconds.
