BBC Good Food site (although their recipe is for a boneless crown) includes 200ml liquid but I've found a recipe on Slowcookerclub that doesn't have any (other than the butter under the skin).
Has anyone got a tried and tested recipe for a turkey crown in the slow cooker? There are a lot of recipes so its hard to know which will work and i havent used mine for whole joints of meat yet, inly sauce-based recipes.
