Leeks! The only winter vegetable that hasn't died on me. Sow in March or April, harvest all winter. Makes a nice leek and potato soup.

Home-made Christmas decoration. If Dulux are wondering where their paint colour cards are, don't tell them.

I'm in Seville! There is sunshine, seville oranges and seven-hundred year old buildings. ☀

For the vegan in your life: fake cheese that really does taste like cheese
