Instructions for red coconut curry:
Add red bell peppers, garlic, ginger, yellow onion, olive oil and salt into a large stock pot.
Saute over medium high heat until vegetables start to sweat and soften.
Add coconut milk, lemon grass stock or water, red curry paste, sugar, fish sauce, Thai basil, soy sauce, lime juice, optional dash of red curry powder, stir and taste to adjust the spice level and sweetness, remember the sauce will reduce and flavors will intensify.
Add bamboo shoots and bring mixture to a boil.
reduce heat to a simmer and cook for 10-15 minutes or until mixture is reduced by 1/4, meaning you have 3/4ths the amount you started with. The sauce will look thicker and you can taste to check the constancy and see if it's where you would like it, some people like it thinner, some like it thicker.
Do a final taste test to check for balance, add ingredients as needed.
Garnish with more basil.
Add cooked chicken or beef and cook for 1-2 minutes then serve with rice.
