The process of making something sweet or sweeter; the action of sweetening.
From Latin 'dulcis' (sweet) plus 'facere' (to make), with the '-ification' suffix. This technical term developed primarily in chemistry and cooking contexts.
The '-fication' suffix literally means 'making' something—so dulcification is 'sweet-making,' but we rarely use this fancy word when we could just say 'sweetening'!
