if you love your freezer.
if you have anywhere from 8- 25 (or more) stray tomatoes.
if you arent into canning.
THIS is a good post for you to read.
here is how i make my basic roasted tomato sauce.
sometimes it's more like a paste, but ok. here we go.
a baking sheet covered with aluminum foil with about a tablespoon of olive oil spread around on it.
a preheated oven to 325.
around 4 hours of time for cooking. (unless you leave your house when your oven is on, and in that case you may only need around 30 minutes or so.)
step 1: wash your tomatoes.
i use a produce wash with mine.
step 2: core tomatoes
step 3: cut tomato in half and use your finger to get out all of the seeds and juice from those tiny pockets.
step 4: lay your seedless, juice-less tomato down onto your oiled sheet with the skin side up.
step 5: put into oven and roast at 325 for around 3-4 hours. turning your sheet every hour or so.
step 6: when your tomatoes are looking less juicy (see below.), and it's been about 3 or 4 hours, take them out of the oven.
step 7: after letting them cool, gently peel off the skins. they should slip right off. or squeeze the tomato out of the skins if they are giving you any trouble.
step 8: optional! put into bowl, drain off any excess juice, and mash up with a fork. you have to do this in small batches.
now you are pretty much done. you can put these into the freezer just the way they are and use them to make an amazing salsa, or pasta, or whatever. you could put them into a pot on the stove and use an immersion blender to really puree them. and then cook them longer on low reducing them to a delicious paste to use for a pizza sauce (try it with roasted garlic. o my.) skip the freezer and eat it that night! the world is your oyster at this point.
for those of you who are interested, i filled up 2 baking sheets with tomatoes. i ended up with a little over 3 cups of tomato puree. i used a better boy tomato. if you use a roma, polish linguisa, or other heirloom tomato with a saucy less juicy quality you will get quite a bit more.
go and make your freezer happy.
