Corn: On or Off the Cob

There’s nothing like eating fresh, flavorful corn-on-the-cob, grilled outside on a breezy summer day. But if you want to preserve some of that classic summertime treat for other seasons as well, then you might like to know about a few different ways to freeze corn.

Whichever freezing method you choose, select only tender, freshly-gathered corn in the milk stage. The milk stage is recognizable by plump kernels and a milky white fluid that secretes from cut kernels. (Some people even eat the kernels raw at this stage since this is when they are most sweet and moist). Husk and trim the ears, remove silks and wash well.

Blancher

Freezing Corn-on-the-cob is the only way to still bite it directly off the cob after freezing, but it is likely to become water-logged and mushy because it takes longer to blanch, freeze, and re-heat due to the presence of the dense cob. To freeze corn-on-the-cob, water blanch small ears (1¼ inches or less in diameter) for 7 minutes, medium ears (1¼ to 1½ inches in diameter) for 9 minutes and large ears (over 1½ inches in diameter) for 11 minutes. Cool promptly and completely to prevent a “cobby” taste. Drain and package. Seal and freeze.

Freezing Whole Kernel Corn is likely to produce crisper kernels than corn-on-the-cob, but must be eaten with a utensil or used as an ingredient in a recipe. To freeze whole kernel corn, water blanch 4 minutes. Cool promptly, drain and cut from cob. Cut kernels from cob about 2/3 the depth of the kernels. Package, leaving ½-inch headspace. Seal and freeze.

Freezing Cream Style Corn creates a creamy texture as a backdrop for the crisp kernels which stands alone as a side dish quite well, but does not necessarily mix into other recipes as well as whole kernel corn. To make cream style corn, water blanch 4 minutes. Cool promptly and drain. Cut kernel tips and scrape the cobs with the back of a knife to remove the juice and the heart of the kernel. Package, leaving ½-inch headspace. Seal and freeze.

Another way to prepare cream style corn for freezing is to cut and scrape the corn from the cob without blanching. Place the cut corn in a double boiler, and heat with constant stirring for about 10 minutes or until it thickens; allow to cool by placing the pan in ice water. Package, leaving ½-inch headspace. Seal and freeze.

For Fresh Rhubarb Pie All Year-Round

If you’re a fan of the tart, tangy flavor of rhubarb, then these preserving tips are for you. Once safely preserved, you’ll be able to add that one-of-a-kind taste to delicious pie, tart, and muffin recipes any time of year. You may even like to experiment with sauces or spreads. For a baked-good, sauce, and spread friendly product, try either canning or freezing your rhubarb according to the directions below.

If you are new to canning, or could use a refresher of the basics, then please read Using Boiling Water Canners and Principles of Home Canning before beginning.

Canning

Select young, colorful stalks and trim off the leaves. Wash and cut the stalks into 1/2 to 1 inch pieces. You’ll need to know how much rhubarb you have in order to figure out how much sugar to add, so measure your sliced rhubarb and then place in a saucepan. For each quart (4 cups) of rhubarb, add ½ cup sugar to a saucepan. Wait for juice to appear, and then heat gently to boiling. Immediately pack hot rhubarb mixture into hot jars, leaving 1/2 inch headspace. Release air bubbles, wipe jar rims, adjust lids, and process in a boiling water bath for 15 minutes. If you are using a pressure canning, please refer to the time tables at http://nchfp.uga.edu/how/can_02/rhubarb_stewed.html.

Freezing

Rhubarb can be frozen with or without sugar syrup. Either way, begin by selecting tender stalks with few fibers. Wash and cut into lengths that fit your freezer packaging (air-tight, moisture proof plastic or glass containers). To help rhubarb retain color and flavor, heat it in boiling water for 1 minute and cool promptly in cold water.

For a dry pack, tightly pack the raw or preheated rhubarb into containers, leaving ½ inch headspace. Seal and freeze. You could also tray freeze the slices in a single layer on a baking sheet just until hardened, then pack dry into your containers. Tray freezing is the best way to have loose slices easily removed from the package.

For a syrup pack, pre-make a  40% syrup: mix a proportion of 2 ¾ cups sugar to 4 cups lukewarm water and stir until the solution is clear. Chill syrup. Tightly pack the raw or preheated rhubarb into containers, and cover with cold 40% syrup. The amount of headspace needed depends on the size of the container and if its top is narrow or wide. See the table at http://nchfp.uga.edu/how/freeze/headspace.html to determine how much headspace you need.
