Peas grow in pods which are like small green ‘cases' which the peas grow inside
You need to look for the pea pods which are swollen as these should have fully formed peas inside
Pick these pods as soon as they are ready as they will be at their sweetest then
Pick all of the pod from the top as this will encourage more pods to grow
Pick frequently as this also encourages more pods to grow
If pods haven't swelled and formed peas then it is still possible to eat the pods, these are known as ‘mangetout' peas
