Not really a cooking hack but freezing grapes works really well and they’re a yummy and easy snack especially in summer. If you think your grapes might go off before you can use then or you got a batch that isn’t as crisp as you’d like just freeze em.
If you’re on PC click the cog under your name on the right to open the menu then select “yes” for “Auto media preview”.
If you’re on mobile click the three lines in the top left corner, then click the cog and select “yes” for “Auto media preview”.
I just noticed while writing this that this setting doesn’t seem to carry over between PC and mobile, so if you switch between both you’ll have to change the setting on both platforms.
