Sambal is becoming more common, a spicy Malaysian chile paste that is widely used for a lot of Asian cuisine. You can find it in the Asian food aisle of any well-stocked grocery store. A generally straightforward mix of chiles, salt and vinegar (some have garlic and/or sugar), sambal can best be described as an Asian harrissa. It’s different from Sriracha in that it is nice and chunky with lots of seeds and bits of chile. It makes for a great shortcut to Arrabbiata and here’s the simple way to do it.

The word chutney comes from the Sanskrit word chatni, and in India, refers to relishes that are used to accent other dishes. They can be sweet, sour, hot, or mild. This is a hot and sweet version.  Serve with curries or other Indian foods.

Here is the classic hot sauce of Chile, one that is served with grilled 
or roasted meats. The type of chiles used varies considerably, depending 
on availability and the cook's preference.

This is not the commercial sauce from Jamaica but rather a specialty 
from Georgetown, Guyana. It is served over seafood or used to spice up 
gravies and salad dressings. Note: This recipe requires advance preparation.

This universal salsa, also known as salsa fria, salsa cruda, salsa 
fresca, salsa Mexicana, and salsa picante, is served all over the 
Southwest and often shows up with non-traditional ingredients such as 
canned tomatoes, bell peppers, or spices like oregano. Here is the most 
authentic version. Remember that everything in it should be as fresh as 
possible, and the vegetables must be hand-chopped. Never, never use a 
blender or food processor. Pico de Gallo (“rooster's beak” for it's 
“sharpness”) is best when the tomatoes come from the garden, not from 
the supermarket. It can be used as a dip for chips, or for spicing up 
fajitas and other Southwestern specialties. Note: It requires advance 
preparation and will keep for only a day or two in the refrigerator.

This is a Memphis-style sweet sauce that works well on ribs, pulled pork and chicken.

Here is my version of the classic hot sauce of Rórigues Island in the 
Mascarenes. It is very thick, so feel free to thin with more water if 
you want. You’d think that this sauce might be sour, but it’s not–the 
sugar in the red chiles seems to temper the tart lemons. Any fresh red 
chiles can be used, and you can adjust the heat level to your liking. 
The yield is high here, but the color is so beautiful that you should 
put the excess in decorative bottles as gifts for your friends. It will 
keep for several weeks in the refrigerator. Serve it over fish or other 
seafood.

The chiles, tomatoes, and squash seeds make this a very New World dish, 
as squash has been a staple of the Mexican diet since it was 
domesticated millennia ago. Typically, cooked chicken or turkey is added 
to this sauce from southern Mexico.
