How to Skin Tomatoes

Featured
Picture of How to Skin Tomatoes
It's summer!  Time to grow or buy huge quantities of delicious tomatoes for your favorite summer tomato dishes.  Peeling or skinning tomatoes turns out to be the easy part - in fact, it's so easy a 3-year-old can do it.  Just follow these easy instructions, and you'll be making great tomato soup, salsa, or pasta sauce in no time flat.

i just processed about 22 pounds of tomatoes in about half an hour, including extra time to accommodate my assistant's* help. :)


*Corvidae just turned 3 yesterday!  She loves helping out with fiddly food-prep processes, especially if they involve the stove and/or ice.  If you let your toddler (or older kid) help in the kitchen, make sure they've got a nice stable platform (we use a folding utility stool for Corvidae) and that they're smart around hot and/or sharp objects.  We're trying to scald tomatoes, and hopefully NOT innocent bystanders.

Step 1: Tools and Ingredients

You'll need:

- a pot full of boiling water
- a bowl full of ice water, and more ice to add as needed
- a slotted spoon
- a sharp knife
- lots of beautiful fresh tomatoes!  

I got these Early Girls from my favorite tomato growers, Wild Boar Farms.  Soon they'll have tons of gorgeous and amazingly delicious heirloom tomatoes at the market, but I prefer to roast and freeze those, and their skins are so thin they don't require peeling. If you don't live in the SF bay area, I highly recommend buying some of their seeds so you can grow your own.

Step 2: Staging (set up your system)

- Fill a medium to large-sized pot with water, cover, and crank the heat so it comes to a boil quickly and efficiently.

While you're waiting for the water to boil:
- Fill a medium to large-sized bowl half-full with ice, then cover with water.  Place it near the stove, but not so close it heats up from the boiling water.
- Wash your tomatoes, and remove stems.
- Make a small X in the skin at the flower end (opposite the stem) and place near the stove. (see photo for detail)

Check out my staging choices in the picture below, then modify as needed to suit your situation.

Step 3: Boil tomatoes

Dump tomatoes into boiling water, and cook for roughly 30-45 seconds.  (Start counting time immediately - no need to wait for the water to reboil.)

This time will vary according to the size of your tomatoes (smaller tomatoes will cook faster!), the size of your pot (larger quantities of water have greater thermal mass!), and the number of tomatoes you drop in each time (more thermal mass of tomatoes drops the water temperature!).

The goal is to boil the tomatoes just long enough to cook the outer millimeter or so of tomato skin and connective tissue so the skin will detach easily, while leaving most of the tomato in a nearly-raw state. Do some test runs, and adjust your timing as needed.  If you see the tomato skins starting to split down from your original cut, they're definitely done - yank them out immediately, and consider dropping the time for your next batch.

Step 4: Cold shock tomatoes

Scoop your tomatoes out of the hot water with your slotted spoon, making sure to drain any excess, and drop them into the ice bath.  Leave them until cool, then set out on the counter stem-end down while you process the rest of your tomatoes.

Remember to add more ice (and remove an equivalent volume of water to avoid spills) on a regular basis to keep the water bath nice and cold.

Step 5: Peel!

Now the peels should practically slide off of your tomatoes!  Sometimes a paring knife comes in handy for damaged areas, or tightly adherent skin around the stem, but it's still ridiculously easy.

I prefer to peel over one bowl, then store the peeled tomatoes in a second bowl to avoid mess.  This way, you can squeeze out the accumulated tomato skins when you're done to make a nice glass of tomato water!  Just add a pinch of salt, and it's your treat for virtuously processing all those tomatoes.

Nice !
But really you don't have to go through all this pain to peel tomatoes.
Just dip them in boiling water holding each one with a fork. Let them sit there a few seconds to a minute and a half depending on the variety and ripeness of the fruit. Then retrieve each with the fork and put it on a clean towel … and that's it ! …
The 4 holes made by the fork will be a starter to peel them as well as the nice cross. By the time they're all on the towel they'll be cold enough to be handled.
I've been doing tomato salads this way since 1970, and about 4 to 7 times a week !…
But then again, I really don't see any flaw in this Instructable : "crossed" tomatoes, iced water … Very professional !…

Now what you can to after that, which can be seen as a complementary refinement to tomato peeling for a salad is to take off the seeds. Do this over a bowl after cutting the tomato in four or five big chunks (depending on how many hollows the fruit has. This will enable you to drain the juice : you will use it for the seasoning of the salad. Oil as usual, vinegar but not as much as a regular oil and vinegar seasoning as it will be complemented by the juice from tomatoes : this will make a very sweet oil and vinegar seasoning. If you feel this lacks of acidity add a lemon squeeze … 

Enjoy !…

Great instructable! I've never tried Wild Boar seeds, I'll give them a go next year. Also, love the pictures of your son helping out. I can't wait for mine to be old enough to cook alongside :)

It's amazing how well this technique works! This is my first year processing tomatoes and the boiling water/ice water works like a charm.

These tomatoes look so good. Can't wait until mine are ready to try this. Thanks for sharing.
