I should have harvested all of the green tomatoes before the freeze, but I left them on the plant. The freeze did not visibly damage the fruit, but since ice formed inside the tomatoes each night, causing cellular damage, the decomposition process will soon begin.
I needed to harvest and use them ASAP!
I found a recipe for chili verde that called for green tomatoes rather than tomatillos. The Piemaker dumped the whole batch in - enough for a triple recipe! - and cooked it for an entire day.
