Make a curry powder by combining turmeric, coriander–cumin powder (dhana jeeru), red chili powder, ginger powder, ground cumin, ground cinnamon, and ground nutmeg. Note: This may be substituted with 1 Tbsp. + 1 tsp. of British curry powder.
Combine tamari, curry powder, and pineapple juice. Set aside.
Heat toasted sesame oil in a wok on medium heat. Add onions and shishito peppers. Sauté for 2-3 minutes until translucent. (Onions are optional and may be omitted.)
Add red bell peppers, green bell peppers, and baby corn. Cook for 5-7 minutes or until slightly tender.
Add rice, tamari mixture, and basil. Gently mix until combined. Fold in pineapple and cashews.
Garnish with cilantro & scallions and serve with a hot sauce (optional).
As one fun presentation option, this dish may be served in a real pineapple with a mini cocktail umbrella as shown in the photo. Using a sharp serrated knife and rocking motion, cut a pineapple in half (lengthwise). Scoop out and replace with pineapple fried rice.
