Towards the end of a season (where has summer gone?!), I often think that the most useful dishes to learn are delicious condiments and sauces. We've been in the summer cooking groove for months now, and it's very possible that many of the things we've been making routinely (grilled chicken, fish, vegetables, and meat, or some simple grain and bean salads, perhaps?) could use a little refresh before we get bored. That's where condiments and sauces come in. You can whip up a batch, stash them in the fridge or freezer, and they're at your disposal anytime you want liven up those simply cooked staples of summer.
