Now Forage

Blackberry: Fully black (not red or dark red) and comes off the stem with no resistance — zero pull. Dull rather than shiny; a shiny black berry is still slightly underripe and tart. Eat the same day for best flavour.

Raspberry: Deep red (or gold/yellow for golden varieties) and slides off the receptacle — the hollow centre is the tell. Does not pull: a ripe raspberry separates at a touch. Extremely fragile; use within hours of picking.
