In a way that is extremely pleasant, enjoyable, or delightful—often describing taste or sensations.
From 'delicious' (from Old French 'delicious,' Latin 'deliciosus,' from 'delicia' meaning 'delights'). The '-ly' makes it an adverb describing how something happens.
Modern English has started using 'deliciously' beyond food—we talk about 'deliciously scandalous gossip' or 'deliciously ironic moments'—expanding an old food word into emotion territory.
