Thai red curry paste is found in many specialty food stores and Asian markets. Look for a brand that doesnt contain fish sauce. Thai basil has a fresh, minty taste, and ordinary Western basil is not a substitute. Look for Thai basil in Asian markets and at well-stocked supermarkets. Serve this zesty curry over rice or rice noodles.
Heat large wok or skillet over medium heat until very hot. Add oil, and, when hot, add curry paste, garlic and ginger. Stir-fry 1 minute. Add coconut milk, brown sugar and tamari soy sauce, and cook 2 minutes.
Add squash, and cook 15 minutes, stirring occasionally. Add water if mixture is too thick. When squash is almost tender, add scallions and green bell peppers, and continue cooking until squash is tender but still intact.
To serve, garnish with Thai basil leaves, if using, and toss well.
If your curry paste is spicy and you want to moderate its heat and the richness of the coconut milk, try a German Riesling, which is dry and has good acidity. If you want to accent the richness and body of the dish, consider a tropical Gewürztraminer or Semillon. To heighten the spicy and the herbal notes, try Australian Shiraz.
