In July even the most stringent spender is tempted to buy quantities of delicious food. It’s a month that is synonymous with the best of our home-grown fruits. Such lovely ingredients are best served in a simple fashion, which is fortunate, for warm weather inevitably dulls appetites. Keep main meals light, choosing from chicken, veal, salmon and summer shellfish including lobsters and prawns. Serve them with this month’s garden peas, calabrese, courgettes and French beans.
