Help with ham : do I need to reheat a cooked ham before I glaze it ?

[Peaseblossom22]

Just that really , usually I cook my own but this year we have a precooked one from the butcher . Do I have to reheat it first before putting the glaze on . We will be eating it cold .

if your eating it cold no just put the glaze on it and put back in the fridge to set the glaze

Thank you . So when O glaze it in the oven presumably I don’t need to make sure it gets piping hot in the middle

no just put it in long enough for the glaze to get sticky about 15 minutes and put it straight back in the fridge so the outside cools down very quickly as it is already cooked
