Today’s post is the first in what I hope will be a long series of practical, educational kitchen tips. I’ll share techniques I’ve learned both on my own and in culinary school. This one started as a Pinterest tip I wanted to test, and the results were convincing. If you saw my Low-Sugar Strawberry Freezer Jam recipe, you’ll know I recently bought a flat (8 lbs) of strawberries at a great price. After removing the obviously spoiled berries, I tried this simple cleaning method:
Place whole strawberries, stems and all, in a clean sink filled with a solution of 1 part white vinegar to 10 parts cold water. (For my batch I used about 2 cups of vinegar to 20 cups of water.) The vinegar helps sanitize and reduce mold spores, extending freshness without affecting flavor. The cold water gives the fruit a gentle shock that helps keep it firm. Let the strawberries soak for about 5 minutes.
After soaking, GENTLY spin the strawberries in a salad spinner until they are mostly dry.
Transfer the cleaned, dry strawberries to a bowl lined with paper towels to absorb any remaining moisture, and leave them uncovered in the refrigerator. That’s it—simple and effective.
The sink was noticeably dirty after washing the berries, which shows how much debris and residue this method removes.
I bought the flat on a Wednesday and used this cleaning method the next day. About half of the berries (roughly 4 lbs) remained good for almost a full week. We ate the softer ones right away, cooked some into jam, and served the rest with a Coconut Cream Fruit Dip at a small gathering. Most of the strawberries stayed fresh for four days after washing; by days five and six they began to show some surface wrinkling. These berries were already fairly ripe when I purchased them, so this method helped maximize their usable life.
This same vinegar-and-water soak should work well for other types of berries too. Give it a try!
