Shell moulding vs enrobing

Two routes to a filled chocolate. Moulding builds the shell around the filling; enrobing pours chocolate over a filling that already holds its shape.

Side by side

	Shell moulding	Enrobing	Why it matters
What the filling must do	Nothing structural. A liquid centre is possible.	Hold its own shape before coating.	This is the decisive constraint. Anything genuinely fluid — a caramel, a spirit centre — has to be moulded.
Appearance	High gloss from the mould surface, and decoration can go in before the shell.	Softer finish; decoration goes on top after coating.	Mirror-finish coloured bonbons are always moulded. The gloss comes from the polished polycarbonate, not from the chocolate.
Coating thickness	Thicker and more variable.	Thinner and very even.	Enrobing gives a higher filling-to-chocolate ratio, which suits a delicate centre.
Equipment	Polycarbonate moulds; feasible by hand.	A curtain enrober at scale; possible by hand with a fork, slowly.

For fluid or soft centres, for coloured cocoa butter decoration, and for a high-gloss finish.

For firm centres — ganache slabs, marzipan, caramels cut to shape — and where a thin even coat is wanted.
