Cooking an already smoked 28 lb ham
How do I go about cooking an already smoked 28 lb ham? My mother bought one, but doesn't know squat about cooking ham. I too don't know squat about cooking it. I know only how to prepare (sauces, etc...) Do you cook it in the oven or over a fire? Note: we have no way of knowing oven temp as we have no temperature readers and we have looked and looked for one, but to no avail. Thanks.
Edit: It's a Swift Premium smoked ham we bought from Price Costco. It has no instructions, at least on the outside. We haven't opened the package, as it is currently thawing. The ingredient label reads: ham, salt, water, sugar, sodium phosphate, sodium erythorbate, and sodium nitrite.
