Tomatillo-Avocado Sauce
The green tomatillo has a bright sharp flavor akin to that of green plums or rhubarbs. In the winter months, when it’s sometimes hard to get fresh red tomatoes, I use tomatillos, which are available all year. This sauce makes the ideal cool counterpart to spicy salsas. The unusual addition of ice keeps the cilantro green when pureed with the other ingredients.
