Zesty Green Tomato Relish

Why This Zesty Green Tomato Relish Works

Salting the chopped green tomatoes and other vegetables at the start pulls out a lot of their water. Over a few hours, the pieces shrink a bit and firm up. After they are rinsed, they don’t leak as much liquid into the pot later, so the relish doesn’t end up watery. The salt soak also lets the onions and peppers soften just enough while still keeping some bite.

Once the vinegar, sugar, and spices come to a boil, the hot liquid surrounds every piece of tomato and pepper. As everything simmers, the vegetables soak in the vinegar and sugar and start to taste less sharp and more bright and tangy. The heat also lets the mustard and celery seeds spread through the pot instead of staying in one spot.

During the short simmer, the tomatoes and peppers soften but don’t fall apart, so the relish keeps a chunky texture. After it cools in the jars, the pieces stay suspended in the slightly thickened, syrupy liquid instead of separating into mush and juice.

Mistakes To Avoid

Skipping the long salt rest or cutting it short leaves the tomatoes and peppers full of water. Once they hit the hot vinegar, they leak liquid into the pot, so the relish ends up thin and watery instead of slightly thick and chunky.

Rinsing the salted vegetables too lightly keeps a lot of salt trapped in the pieces. In the pot, that leftover salt mixes with the vinegar and sugar and the relish turns harsh and overly salty, and the vegetable flavor gets buried.

Letting the relish simmer much longer than 15 minutes makes the tomatoes and peppers collapse. The pieces lose their shape, the mixture turns mushy, and the liquid can cook down so far that the relish becomes pasty instead of spoonable.

Adding the vegetables before the sugar has fully dissolved in the vinegar leaves gritty bits in the liquid. Those undissolved crystals stay in the jars, so the relish has a sandy texture instead of a smooth, syrupy brine around the vegetables.
