TASTE TEST: This so-called 'miracle berry' makes sour food taste sweet 🤯 Synsepalum dulcificum, native to West Africa, is known for temporarily altering the taste of acidic food, even sourest of lemons. It's down to the glycoprotein miraculin which activates the sweetness receptors in our taste buds when it is in low pH conditions. Glasshouse Horticulturists Audrey and Mia put it to the test 💪 Please do not try this at home with berries you find outside. | Royal Botanic Garden Edinburgh
