Although avocado is mostly used in dips and salads in the United States, it makes its appearance in sauces, soups and even stews in regions where it grows. When gently warmed, this creamy, garlicky sauce with a hint of heat is excellent on grilled chicken or fish, and it is equally good as a condiment for burgers. The sauce may be served cold and do double duty as a dip or salad dressing. You will want to thin the sauce slightly if using warm. If using as a salad dressing, add enough water to achieve an easily pourable consistency and cut the chipotle pepper in half or omit it altogether.
