鳄梨 are versatile fruits that are delicious in salads, sandwiches, tacos, or transformed in 鳄梨色拉酱. 但是牛油果是很棘手的东西. They make you wait until they decide to ripen, then quickly speed past the sweet spot into mushy, 悲伤的粘性. 它们也不便宜. 当牛油果放进去的时候, you really want to squeeze the most value out of them by storing them right.

如何选择牛油果

最喜欢的水果, 鳄梨 do not ripen until picked, so fresh ones will be as hard as rocks. 寻找一个偶数, unblemished texture–uniformly hard or soft over its entire surface–and those that feel heavy for their size. Avoid any with bruises or soft spots, and those with a hollow between the flesh and skin. Shake the avocado to test; if the pit is loose, move on to the next one.

The flesh of ripe fruits will yield when pressed gently. 然而, ripe fruits bruise easily with excessive handling in the markets, 所以最好在家里自己煮熟. This means planning ahead and buying them two to five days in advance to ensure they 完全成熟.

如何储存牛油果

Do not refrigerate your 鳄梨, at least not initially. If they are fridged too early, they won't ripen completely. Once picked from the tree, 鳄梨, much like 香蕉, produce ethylene, which triggers the ripening process. A cool, dark place is best for storage, with an ideal temperature of 68 F.

Fresh-picked 鳄梨 should ripen under these conditions within a few days. When ripe, the avocado should yield gently to pressure when you squeeze it but not be squishy. 

If you want to accelerate the ripening process, place the 鳄梨 in a paper bag. 这就浓缩了乙烯气体. If you add other fruits such as 香蕉 and apples, they will all ripen more quickly together. Be sure to keep an eye on your 鳄梨 if you use this method; they will ripen before you know it.

何时冷藏牛油果

Once ripe, un将鳄梨s can be stored in the refrigerator, unpeeled, for up to one or two weeks. 简单地藏在你的保鲜柜抽屉里. The flesh of the avocado quickly begins to darken when exposed to the air, so it is important to work quickly with the meat once the avocado is cut. The addition of an acid (lemon is usually the acid of choice) retards the darkening process.

切好的牛油果应该冷藏. Just like apples, 将鳄梨s oxidize quickly and turn brown. While this does not make them inedible, it is aesthetically unpleasant. 保存 将鳄梨, brush the exposed flesh with lemon juice, cover tightly with cling wrap, and refrigerate. The acidity of the lemon juice helps stop oxidation, as does limiting the amount of oxygen that comes into contact with the flesh of the fruit. Alternatively, you can use a store-bought 鳄梨门将. Regardless, use 将鳄梨s as soon as possible.

冻结鳄梨

Sometimes you end up with too many deliciously ripe 鳄梨 and you'd like to preserve them for a later date. For long-term storage, freezing is the only effective method.

The National Center for Home 食物保存 (NCHFP) recommends mashing ripe 鳄梨 into a puree prior to freezing because whole or sliced 鳄梨 do not freeze well. Add a tablespoon of lemon juice to every two 鳄梨 to preserve the color. 放置在塑料容器中, zip-top bag and remove all of the air before sealing and freezing for up to three months. Defrost before using and use immediately to make 鳄梨色拉酱 再来一个蘸酱,冰沙, avocado-based酱,或简单地用作铺菜.

酸洗鳄梨

Another method of preserving 鳄梨 is to turn them into pickles. 酸洗 is best for 鳄梨 that are just barely ripe and still firm. 它们将在冰箱里保存一个星期.

做鳄梨泡菜, heat a mixture of one part water to one part vinegar along with salt, 糖, and whole spices like peppercorns or coriander. Bring to a boil, dissolve the salt and 糖, and let cool. Halve and slice the firm-ripe 鳄梨, removing the peel and pit. Add to a jar and top with the vinegar mixture. Chill for at least a couple of hours before enjoying, but a day or more is better.

颜色会随着时间的推移而褪色. Make sure any avocado pickles stay submerged in the brine. 腌鳄梨, 不像其他水果和蔬菜, are not recommended for hot water or pressure canning.
