Jonathan and I have a constant argument around jar opening. I like to use our v-shaped opener with teeth and he despises it saying it makes the lid of the jar too sharp. We were telling our friend @mariofeldman (you may remember him from his microwave flan fame) about this and he told us about this trick. He was genuinely shocked not everyone opens jars his way. Whaat? How do you do it? #howtoopenajar #jar #kitchenhack #kitchentip | Cupcake Project
