Cook’s notes
- Leg is much leaner than shoulder; trim any visible fat.
- Lamb is richer than other meats, so two blocks with veg make a lighter meal.
- Slow cooker: 6 hours on Low.

Lamb, Sweet Potato & Rosemary Stew questions
Can I use lamb shoulder instead of leg?
Shoulder stays tender and is more forgiving in a long braise, but it carries a lot more fat. Trim it hard and skim any fat from the top before cooling.
Can I use ordinary potatoes instead of sweet potato?
Ordinary potatoes in the same 2cm dice work well. They're less sweet and break down less, so crush a few more against the side of the pan to thicken the gravy.
Why toss the lamb in cornflour?
The cornflour helps the lamb brown and then thickens the gravy as it braises. It also keeps the stew gluten-free, which plain flour would not.
Updated . Nutrition, costs and yields are estimates. Gluten-free assumes tamari in place of soy sauce and gluten-free stock cubes.
