Dead of winter. It’s an apt description for this time of year, when even apples are out of season and virtually every other fruit comes from another time zone, if not another hemisphere.
The cure for a cook’s cold-weather blues, however, can be found a few aisles over from fresh produce: Winter is frozen fruit’s time to shine. Right out of the bag, frozen fruits are great for snacking, and they are a favored ingredient in breakfast smoothies. But with a little more effort, they can liven up a cake or a batch of muffins, as well as lend a sunny sweetness to savory dishes.
Frozen has some distinct advantages over out-of-season fresh fruit. Bob Barnhouse, vice president of operations for Dole’s frozen division, explained that fresh fruit destined for faraway markets often is picked before it is ripe, and can spend weeks reaching its destination. “With frozen,” he said, “we pick it at the peak of the season, and then usually process it within 24 hours.” The cleaned and sorted fruit is conveyed into a tunnel, where the circulating air is about 30 F below zero. Within 20 minutes the fruit itself has been cooled to zero F. (This process, commonly known as flash freezing, is called IQF — individually quick frozen — in the industry).
Barnhouse said that strawberries were Dole’s top frozen seller, followed by the rest of the berry family, then peaches and other fruits. Ironically, strawberries freeze less well than other fruits since trimming off the stems “opens them up” and leaves them vulnerable to cell damage and water loss. “Most frozen strawberries end up in fruit smoothies and margaritas,” he said. “When they’re puréed, the textural loss isn’t really a problem.”
