But I thought if I could do the roast in the slow cooker then it might not heat up the kitchen quite so much. I haven't tried this before but fortunately the internet is your best friend in these situations. Within five minutes of Google searching I had found a recipe and the lamb (a 2kg leg seasoned with garlic and rosemary) has been cooking since about 9.30 this morning, sitting on top of five balls of scrunched up tin foil so it doesn't stew in its own juices.
It smells AMAZING. Hopefully it will taste as good as it smells. I decided to ditch the idea of roast potatoes and have boiled up potatoes to make potato salad. Some corn, some lettuce and tomatoes and we are having roast lamb and salad for dinner tonight.
Minimal effort. Minimal time spent in kitchen on boiling hot day. Maximum enjoyment.
