In Doy’s garden

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

Whey protein powder is made from the liquid left over in cheesemaking, filtered and dried. A scoop is shaken with water or milk, or stirred into oats and yogurt; flavoured versions add a little sweetener.

Mixed with milk instead of water, the shake gains the milk's numbers too, so log the milk separately.
