Canning Yellow and Orange Tomatoes

Crushed Tomatoes

I have been asked several times in  canning  classes, if it is safe to can yellow or orange tomatoes. We have all heard that yellow and orange tomatoes are lower in acid, so are they still safe to can? The answer is yes, they are safe to can.

Why?

 

Truth is, that yellow and orange tomatoes have just as much acid as red tomatoes.

 

Well, for the most part at least. In terms of acidity or Ph, yellow and orange tomatoes are about average. Some cultivars have more, some less.  Bottom line is that all tomatoes are safe to can- as long as you acidify them.

Adding salt is optional and is for flavor only. Use canning/pickling salt or non-iodized salt when canning.

 

Here are some popular canning recipes to get you started. All follow the NCHFP (National Center for Home Food Preservation) recommended procedures.

Crushed Tomatoes

 

Peel and core tomatoes , trim off any bad spots and quarter. Place about 1/4 of your prepared tomatoes in the kettle and cook, stirring constantly over high heat. Use a potato masher to crush tomatoes and extract juices. Once they are boiling add remaining tomatoes, stirring constantly. You don’t need to crush these tomatoes. Bring to a boil and boil for 5 minutes. In clean, hot jars add needed acidity listed below. You can also add 1 teaspoon of canning salt per quart if desired. Ladle in hot tomatoes, leaving 1/2-inch headspace. Wipe jar rims clean and adjust lids. Process in boiling water bath. Pints 35 minutes, quarts, 45 minutes. 1,000-3000 ft over sea level add 5 minutes. Twenty-two pounds of tomatoes will yield about 7 quarts of tomatoes.

 

Whole Tomatoes in Juice

 

Use any extra tomatoes to make juice. I use tomatoes that are too big to can whole, or those that have blemishes that need to be trimmed. Cut up clean, unpeeled tomatoes in a kettle and cook, stirring often until tomatoes are mushy. Strain mixture, pressing on solids or run through a food mill or tomato juice extractor. Set aside,. Place peeled, whole tomatoes in kettle and add enough tomato juice to cover them. Heat to a simmer and simmer gently 5 minutes. Add lemon juice or citric acid to jars, using amounts listed below. Add salt, if desired. Add tomatoes and cover with hot juice, leaving 1/2 -inch headspace. Wipe rims and adjust lids. Process both pints and quarts 85 minutes in a boiling water bath.

 

Tomato Juice

Wash, stem and trim bruises off tomatoes. Cut into chunks. Add about 1 pound of tomatoes to kettle and bring to a boil while crushing. Continue to add additional cut up tomatoes slowly, keeping mixture boiling. This will keep the juice from separating later. Simmer an additional 5 minutes once the tomatoes have all been added. Press mixture through a strainer , sieve or food mill to remove seeds and skins. Add lemon juice or citric acid to jars according to directions listed below. Add salt if desired. Return juice to boil and add to prepared jars leaving 1/2-inch headspace. Wipe rims and adjust lids. Process n a boiling water bath pints 35 minutes and quarts 40 minutes. Add 5 minutes processing time at elevations between 1,001 and 3,000 ft.

Tomato Sauce

 

Prepare as for juice. After juice is made return to pot and start cooking down to desired thickness. You’ll lose about 1/3 of the volume for thin sauce and 1/2 of the volume for thick. Add lemon juice or citric acid to prepared jars as described below. Add salt if desired. Add boiling sauce leaving 1/4 -inch headspace. Wipe rims and adjust lids. Process in a boiling water bath 35 minutes for pints and 40 minutes for quarts. Add five minutes at 1,001-3,000 ft. elevation.

Acidity and Tomatoes

Tomatoes must be acidified before canning. When canning either whole, crushed or juiced tomatoes you must add either 2 T. bottled lemon juice per quart or 1/2 t. citric acid . For pint use 1 T. lemon juice or 1/4 t. citric acid. You can also use 4 T. (5%) vinegar per quart, but it will alter the flavor and is not recommended. You can add a little sugar to offset the flavor, if you like.
