In Doy’s garden

Log it in Doydum and a row of strawberries sprouts in today’s bed in front of Doy’s house.

Watermelon is the taste of a Turkish summer, sliced cold and eaten with white cheese and bread on warm evenings. It is mostly water, so even a big slice is cooling and refreshing.

Slices vary hugely, so weigh the flesh once without the rind to get a feel for your usual slice.
