Cook the tomatoes 2 minutes and take of the skin.
Chop the tomatoes, the chili peppers, the onion and the garlic. Put
all ingredients together in a kitchen machine and mix shortly.
Salsa has most probably an Aztec Indian background
and is made of tomatoes and chillies as main ingredients. Salsa means
"sauce". Salsa is cooked shortly and is not sweet or caramelized.
Chutney comes from the Indian "chatni", which means "strongly
spiced". Normally, it is made out of fruit pieces, vinegar, sugar, peppers
and/or other spices.
Chutney is nice with Indian food but also as a replacement of mustard
with cheese.
Relish is more or less the same as chutney;
the cooking time may be a bit shorter though. Therefore, chutney is
normally softer and the sugar may be caramelized.
