Blueberries are easy to freeze and maintain great quality for year-round use in favorites such as muffins, pancakes, and smoothies. They are nutrient dense and add freshness and flavor to meals.<\/p>\n\n\n\n

Blueberries can be prepared for freezing using two methods<\/a>: i) Dry pack and ii) crushed or pur\u0341eed. If you can\u2019t freeze right after picking, refrigerate at 40 degrees F or below until ready to prepare and freeze. Work with small batches to prevent loss of nutrients and quality.<\/p>\n\n\n\n

i)\u00a0Dry pack<\/a>\u00a0is the easiest method.\u00a0Most advice says do not wash the blueberries; the skins will toughen if frozen wet. (If you do want to rinse them off with clean water, be sure to completely dry again before packaging and freezing.) Remove leaves, stems, and any bruised or immature berries.\u00a0Package<\/a>\u00a0berries into moisture vapor resistant packaging, either rigid plastic or flexible bags.\u00a0 Leave\u00a0headspace<\/a>.<\/p>\n\n\n\n

Tray freezing<\/a> before dry packaging allows blueberries to remain loose; and easier to remove in smaller amounts.  Spread a single layer of berries on shallow trays and freeze.  Once frozen, remove and promptly package.  Return to the freezer immediately.  When ready to use, remove from packaging and wash blueberries thoroughly by gently rubbing under cold running water.<\/p>\n\n\n\n

ii) Crushed or pure\u0341ed <\/strong>is another method for freezing blueberries.  To prepare for freezing, remove leaves, stems, and any bruised or immature berries.  Wash blueberries thoroughly by gently rubbing under cold running water. Drain in a colander and blot dry with paper towels.<\/p>\n\n\n\n

Crush, press through a fine sieve, or process in a food processor or blender. Mix with 1 to 1-1\/8 cups sugar with each quart (2 pounds) of crushed berries or pure\u0341e.  Stir until sugar is dissolved.  Package in freezer containers, leaving headspace<\/a>.  Label, seal, and freeze promptly. <\/a>  Keep an accurate inventory of the freezer.  Use first in, first out method to use blueberries at peak quality.<\/p>\n\n\n\n

If you plan on using your frozen berries at a later time to make jam or jelly, freeze them unsweetened or follow the proportions of sugar to berries in the jam recipe you will eventually use.<\/p>\n\n\n\n

Taking time to freeze fresh blueberries with care will provide delicious, high quality, and nutritious fruit for use year-round.<\/p>\n\n\n\n
