Prices vary from 80p-£2.20p lb, depending on the thickness and quality. Always choose crisp, fresh looking spears with tight buds at the tips. The hot weathjt means that many spring vegetables are in plentiful supply. Cauliflower, spring cabbage and greens are all good quality. Lettuce is also an excellent buy at the moment, as are cucumbers, celery and spring onions. Food prices 258/9
