Special instructions for canning Roma tomatoes whole. Canning tomato sauce from home garden Roma bush tomatoes. Roma tomato press, juicer, strainer.
Roma tomato is one of the best varieties to use when making oven dried tomatoes or home made tomato sauce because, being a paste tomato, it contains less juice than other types of tomatoes.
This means less cooking down is required to thicken the sauce.
It takes at least 6 Roma bush tomato plants to produce enough fruit for canning, so be sure to plan a big enough tomato garden if you plan to grow your own.
Roma tomatoes taste good alone but some home gardeners find that their canned tomato sauces are more richly flavored if they use a mixture of Romas and other heirloom tomatoes. The Brandywine tomato seems to be a particular favorite.
For canning whole tomatoes, 21 lbs. of fruit will fill about 7 quart jars.
For tomato sauce canning use 46 lbs. of fresh Roma tomatoes.
If you chose to combine beefsteak tomatoes with Romas when making homemade tomato sauce, substitute beefsteaks for up to 1/3 of the Roma tomatoes.
Choose vine ripe but not over ripe, uncracked fruit. Wash it and cut out the core and any bad spots.
Follow the instructions on How to Peel Tomatoes to peel and seed the tomatoes if you are making sauce. If you will be canning whole tomatoes, just peel them. I like to remove the stem scar with a paring knife as I find it a nuisance when I go to use the tomatoes in recipes. You can remove it or not as you see fit.
Chop the peeled and seeded tomatoes and simmer them in a dutch oven until the sauce is as thick as you want it to be.
You may add any seasonings you wish at this time and also white or brown granulated sugar to cut the acidity.
Pour the sauce into hot, sterile canning jars and process it in a hot water or pressure canner. Follow the instructions given on Canning Tomato Sauce if you have not canned tomatoes before.
This is the best pressure canner on the market in my opinion. Made in America. Big (30 quarts). Heavy. This is the canner for people who process in large batches.
This Granite Ware Canning Kit is a great value for the money. You get a 21 quart water bath canner and all the tools a beginner needs.
It will work with both gas and electric ranges but cannot be used on smooth top stoves.
The Ball Jar Collection Elite 21 quart Canner is perfect for people who have ceramic stove tops. The bottom is flat and it fits the large burner well.
If you are worried about canning on one of these stove tops, don't be. I have a Kenmore on which I boil large, heavy pots of water on at least every other day. I've been doing this for years and I've never had a problem.
Of course, this stainless steel canner can be used on other types of gas or electric stoves as well. Much longer lasting than graniteware.
After peeling, pack the fruit tightly into hot, sterile canning jars leaving half an inch of space at the top.
See the chart on this page for the correct processing time.
If you make homemade tomato sauce every year, a Roma tomato juicer, press or strainer will make the job a lot less daunting.
Any tomato juicer or food mill you prefer can be pressed into service for canning Roma tomatoes. Tomato juicers come in a range of styles and prices. It is worth investing in one if you will be canning tomato sauce regularly as the juicer will remove the skin and seeds so much more quickly and efficiently.
Just wash the fruit and quarter it first.
The Roma Food brand strainer (above) is not a heavy duty food mill but it is inexpensive and may be all you need if you are canning Roma tomatoes in small amounts.
The Imperia Electric Tomato Strainer is much more durable. This is the tomato juicer you need if you grow and can lots of tomatoes.
