Pomelo. A citrus fruit similar in appearance to a grapefruit with one slightly pointed end. Once the thick skin is peeled the segments need to have the tough leathery coating pulled away. Inside, the flesh can be deliciously sweet and juicy. It is better left for a few days after picking before it is eaten. There are pink and white versions. The peel is candied and eaten as a delicacy. This is one of my favourite fruits.
Winter purslane. An annual plant which provides salad leaves which are mild in flavour and heart-shaped, with small flowering shoots.
Potash. A raising agent used to make a baked mixture light. Baking powder consists of bicarbonate of soda (US: baking soda) and cream of tartar which, if mixed with flour or starch, assists pastry and cake doughs to rise, as when it meets moisture it produces carbon dioxide which aerates and lightens the dough.
