This is the 1st in a series of recipes and other ways to not only cope but LOVE the abundance from the garden this time of year!  It will move to the RECIPES tab of the blogsite soon.

How to Concentrate and Save Tomatoes, Part 1

This stuff will blow up anything you stir it into.

Just don’t call it tomato paste

by Francis Lam  August 20, 2012

It was a triumph: After three hours of chopping, pureeing, simmering, stirring, caramelizing and concentrating, I stepped back from the stove. In my hand was a spoon, clinging to a dynamite-red flavor bomb. It was just short of nuclear, and already I knew I was going to put it into everything that could use a big bang of tart, savory, and sweet with a miles-deep umami finish. I showed it to my special ladyfriend. “Congratulations!” she said. “You just made tomato paste. It’s cheap and comes in cans.”

But but but…Ok, fine. Yes, that is what this is. But to be honest, I’ve never understood, really, why anyone eats the tomato paste comes in cans. I mean, I’m not even snobbing on this—it just tastes like sour goop; has anyone ever said, “You know, what this dish needs is some really sour red goop?”

This homemade tomato paste, though… this is magnificent stuff. Once you’ve concentrated 3 pounds of fresh, sweet, peak-summer tomatoes down to about a cup, you have a texture like cool butter and flavor that makes you feel like your brain might short-circuit: It’s tomatoey, sure, but it’s so tomatoey that it threatens to reform your idea of what a tomato tastes like altogether. The long, slow cooking simmers off all the water, making its flavor vibrate with intensity. But the cooking also starts to caramelize some of the sugars, giving its sweetness a darker, mysterious edge, and since I make it with some olive oil, the paste emulsifies a little to give a rich, round finish. Basically, it becomes a secret weapon for instant deliciousness—drop a spoonful in any sauce, any soup, sauté, salad dressing, or just smear it on something.

And since the cooking process concentrates the acid and boils off water, the stuff keeps well in the fridge for weeks, or in the freezer for months. I love to freeze it in little 2-ounce containers, pulling one out every once in a while to have on hand whenever a dish needs to go bang!

The Bomb Tomato Concentrate
Makes about 1 cup

½ head garlic (optional)
1 medium onion (optional)
3 pounds super ripe, juicy tomatoes
¼ cup extra virgin olive oil
2 pinches salt

Cut, chop, puree: If using, mince garlic and onion in a food processor and reserve. Roughly chop tomatoes, and puree them to liquid in the food processor. (If you don’t have a food processor, no sweat. Just finely chop everything, and save as much of the tomato juice as you can.)

Warm oil: In a wide, heavy pot, warm the oil over medium-low heat. You want the pot to be wide so that the water evaporates more quickly. And you want it to be heavy to cook evenly without scorching (which will really ruin the paste, and your day). If using, add the garlic and onion and cook, stirring, until very soft, 15 minutes or so. Add a pinch of salt. If you want to go full-caramelize on the onions, hey, it’s your world.

Strain tomatoes (optional): If you’re unhappy with tomato skins and seeds, pass the pureed tomato through a fine-mesh strainer. (I won’t judge if you don’t bother.)

Cook tomatoes:  Pour the tomato into the pot, turn heat up to high, and bring to a boil. Add a couple light pinches of salt. Reduce heat to a simmer, give it a stir, and wait. You’ll cook it for a long time, but it’s hard to say how long since tomatoes differ in water content. Bank on 90 minutes or more.

Wait: Wait.

Wait some more: Wait. And stir, too, more frequently as the tomato loses its juice and thickens. I use a heat-proof rubber spatula, since it clears the pot more thoroughly. Keep cooking and stirring. It’ll get thick and annoyingly splattery for a while, as it gets to a pizza-sauce thickness. You can partially cover the pot when that happens, then uncover it again when enough water’s boiled off so that it no longer splatters.

You’re almost there: When it starts to look pasty, you’ll notice that it’ll get stickier. Keep stirring, clearing the pot, mixing back in the thin, darkening layer at the bottom, and spreading the paste out. At some point, it may look like the oil wants to weep out; this is good. When the paste suddenly sticks together like a dough and slides around the pot, you’re done. Congratulations!

Store: Turn paste into a dish or bowl and let cool. Pack into containers, press a layer of plastic wrap directly on to the surface, and store in the fridge for weeks, or in the freezer for months. Stir into anything.

    I will definitely keep this in mind. Looks amazing!

    This does look wonderful – it reminds me a bit of the time (once only) that I had a go at making ketchup – not a fast process! However, I am also not a fan of those little cans of goop, so if I get landed with too many tomatoes, I will definitel give this a go.
