Which compost amaryllis 'apple blossom' needs
For amaryllis 'apple blossom' the mix to buy is peat-free multipurpose compost cut roughly half-and-half with horticultural grit or perlite. A loam-based or quality peat-free compost amended with grit or perlite drains well. Pot snugly with the upper third of the bulb above the surface to discourage basal rot.In British garden centres the bagged growing medium is sold simply as “compost” (multipurpose, ericaceous, or loam-based John Innes), which is a different thing from the rotted garden “compost” you make in a heap — for a pot you want the bagged kind.
Peat-free compost
Buy peat-free. The sale of peat compost to home gardeners is being phased out across the UK, and the RHS recommends peat-free on environmental grounds. A good peat-free multipurpose grows amaryllis 'apple blossom' perfectly well; the one habit to change is watering — peat-free dries faster at the surface while still moist below, so check by feel a knuckle deep rather than trusting the look of the top.
Ericaceous or multipurpose?
Amaryllis 'Apple Blossom' does not want a rich, water-holding compost — it wants sharp drainage. Cut peat-free multipurpose roughly half-and-half with horticultural grit, sharp sand or perlite, and always pot into a container with drainage holes. A "cactus and succulent" bagged mix is a ready-made shortcut.

Can I use ordinary multipurpose compost for amaryllis 'apple blossom'?

Always a pot with drainage holes. Rich, free-draining potting mix. Stand it on a saucer, empty any water that collects after watering, and never leave the pot sitting in a full outer cover — waterlogged compost in a cool UK room is the commonest cause of root rot.
