How to store corn?
Refrigerating corn on the corb
In order to keep corn on the cob fresh in the storage, keep the following things in mind.
- Always refrigerate your corn if you are not going to consume it immediately. The low temperature of the fridge will keep the content of the simple sugars high whilst slowing down their breakdown into bland tasting starch.
- Do not remove the husk. You can remove the outermost dirty leaves but keeping at least a few leaves intact will lock the moisture inside the corn kernels.
- Wrap a plastic sheet around the corn on the cob. Wrapping too tight will result in collecting water inside that will lead to fungal growth, so, keep it a little loose.
Freezing corn on the cob
There are two ways to freeze store corn on the cob.
- Simply place the corn on the cob with the husk intact inside the freezer bags. Label and store for about 8 months.
- The second method is to blanch before freeze storing. For this, blanch the corn on the cob in boiling hot water for 4 minutes. Remove from the water and let it sit in ice-cold water for 4 minutes to stop the cooking process.
Now remove the corn kernels off the cob and store them in a freezer bag. Store in small portion sizes and label the bags.
