Strawberry season comes early in Southern California. To kick off my #StrawberrySeason blog post I did a little experiment. For the past month, I have taken in-season strawberries and tested different methods to make them last longer in the refrigerator. There was definitely one clear winner. Today, I’m sharing my results with you in this post for How to Make Strawberries Last Longer!
Recently, strawberries at my local Sprouts were on sale. Scratch that, they were a steal at $0.88 for a 1-pound container! You better believe I stocked up! 14 pounds (yes, pounds) of strawberries. I had big plans for these berries, and I’ll be featuring recipes like:
- Strawberry Syrup
- Strawberry Lemonade
- Strawberry Frappe
- Strawberry Cupcake and Buttercream
- Strawberry Pizza
- Strawberry Milk
- Strawberry Poke Cake
- and more!
I knew I had to pace myself so I don’t overload my family with strawberries! That’s where this Strawberry Experiment for How to Make Strawberries Last Longer comes in.
(P.S. This would be a fabulous science fair project to do with your kids!)
The Strawberry Experiment: How to Make Strawberries Last Longer
How to Make Strawberries Last Longer – Will strawberries keep longer when kept in a glass jar or treated with a vinegar wash?
- I researched 2 popular Pinterest Methods for How to Make Strawberries Last Longer in the refrigerator.
If I treat strawberries with a vinegar wash they will:
A- Keep longer in the refrigerator than berries kept in a glass jar or in their original container.
B- Not keep longer in the refrigerator than berries kept in a glass jar but keep longer than berries in their original container.
I used berries from the same 1-pound clam shell to test the 2 variables and the control. Berries were of varying sizes, and generally the same ripeness. Any berries that had begun to spoil, I discarded.
Berries were simply placed in a glass jar, unwashed, and placed in the coldest part of the refrigerator.
Berries were placed in a vinegar wash:
- 1/2 cup white vinegar
- 5 cups water
They sat in the vinegar wash for 5 minutes. Then I drained them and gently pat them dry with paper towels. Finally, I placed them in a paper towel-lined bowl and left uncovered in the coldest part of the refrigerator.
Berries were kept in the original packaging, unwashed, and placed in the coldest part of the refrigerator.
After 1 week I placed all the berries side-by-side and compared them. Here’s a better shot:
The Results for How to Make Strawberries Last Longer:
The berries look perfect! Just like they did a week ago. The stems and leaves are still bushy and green. The berries are plump and they have not started to shrivel. They taste perfectly ripe.
The berries look okay. They’re starting to shrivel and the stem and leaves are beginning to dry out. They taste fine.
The berries have seen better days. They’ve begun to shrivel and some strawberries are beginning to go bad. The stems and leaves have begun to dry out. They taste over-ripe.
Conclusion – How to Make Strawberries Last Longer:
The glass jar method is the clear winner. Not convinced? Then check out the same berries kept in the glass jar for 3 WEEKS! They nearly look perfect!
After 3 weeks they’re starting to shrivel a little, and the stem and leaves are starting to dry out. With that said, they tasted good, with a hint of being over-ripe.
The glass jar method is the clear winner. Berries that last 3 weeks in the refrigerator is a total win!
How to Make Strawberries Last Longer – Strawberries in Glass Jar Storing Tips:
- Do not remove the stem, and do not wash the strawberries before storing them.
- Use a clean glass jar that’s been washed and dried thoroughly. It needs to have a tight-fitting lid. I like using mason jars like these. Large jars like pickle jars are perfect for larger quantities of strawberries.
- Discard any spoiled or bruised fruit. Do not put them in the jar with the other strawberries.
- Place the jar in the coldest part of your refrigerator.
- The strawberries will not get moldy using this method. They will, however, start to ferment. They may seem fine but they aren’t edible if you leave them too long in the refrigerator.
***NOTE: results will vary based on ripeness of fruit when placed into the jar, refrigerator temperature, etc.
