In 1946 David returned to England, where food rationing imposed during the Second World War remained in force. Dismayed by the contrast between the bad food served in Britain and the simple, excellent food to which she had become accustomed in France, Greece and Egypt, she began to write magazine articles about Mediterranean cooking. They attracted favourable attention, and in 1950, at the age of 36, she published "A Book of Mediterranean Food". Her recipes called for ingredients such as aubergines, basil, figs, garlic, olive oil and saffron, which at the time were scarcely available in Britain. Books on French, Italian and, later, English cuisine followed. By the 1960s David was a major influence on British cooking. She was deeply hostile to anything second-rate, and to over-elaborate cooking and bogus substitutes for classic dishes and ingredients. In 1965 she opened a shop selling kitchen equipment, which continued to trade under her name after she left it in 1973.
