Don't really like ice-cream with puddings.
Have Brandy Sauce on Plum Pudding, & usually Cream on others'.
Custard on pudding infrequently. But like it on pies'=Apple, apricot, mulberry. Cream sometimes.
It all depends if I've the product, but always have ice-cream & cream. Have to add to shop-list, if think ahead for it, the custard.
