Place all ingredients in a food processor or blender and process well to create a fragrant Thai red curry paste.
If too thick, add a little more coconut milk to help blend ingredients. Note that it will taste very strong at this point, but will mellow when you add your curry ingredients plus remaining coconut milk. Also, it will turn 'redder' once it is cooked, bringing out the red chili color.
If you prefer a curry sauce rather than a paste, add remaining coconut milk and blitz.
To Create a Curry out of Your Paste: Follow the instructions below, or see my Easy Thai Red Curry Chicken Recipe .
Fry the paste in a little oil to release the fragrance (1 minute). Add your choice of meat, tofu, wheat gluten, or vegetables. Add remaining can of coconut milk to create the curry sauce. (if more sauce is desired, add some good-tasting chicken/vegetable stock). Some vegetables that work well with red curry include: tomatoes, eggplant, zucchini, snow peas, cauliflower, and spinach.
If using fresh lemongrass, add leftover pieces of lemongrass (upper part of the stalk) to the curry as you cook it - this will add more flavor. You can also add a cinnamon stick and 2-3 whole kaffir lime leaves OR substitute 1-2 bay leaves.
Before serving, always do a taste test. If not salty or flavorful enough, add more fish sauce or salt. If too salty, add another squeeze of lime juice. If too sour, add a little more sugar. If too spicy, add more coconut milk. If you've run out of coconut milk, add a little yogurt, sour cream, or cream.
Before serving, sprinkle over a handful of fresh coriander/cilantro and basil. ENJOY!
*About Chili Powder : Since I can't get Thai chili powder where I live, I always use the chili powder from my local supermarket. Although Mexican in origin, I find it works wonderfully well for this and other Thai recipes, as the chilies are roasted first before being blended into powder. If using Thai or Asian chili powder, be sure to reduce the amount to a teaspoon or two rather than tablespoons, or it will be far too spicy.
To Store Paste : Place in an airtight jar or other container in the refrigerator for up to 1.5 weeks; freeze thereafter.
