Thai peppers are tiny, spicy and full of flavor. If you would like to bring down the heat a bit in this dish omit a portion of the peppers. If you like it spicy, two of these firecrackers are quite a kick.
When fresh tomatoes are abundant in the summer and fall, I will use them. Because this is a primary sauce, I use canned tomatoes when fresh are no longer available. You may omit the red pepper for milder flavor or substitute Kalamata olives for the capers and black olives. – Chef Antonio.
