Three days. Frozen elbows can be wrapped in plastic wrap and stored in the refrigerator for three days without deterioration. If the frozen elbow needs to be preserved for a long time, it needs to be scraped clean, cooked in a soup pot until it tastes delicious, taken out and dried, put into a fresh-keeping bag, frozen in a freezer, and taken out as a raw material when eating. If refrigerated, it can be stored for up to 3 days. If it is frozen, it can be kept for up to 3 months.
