There is a reason professionals reach for Valrhona before anything else: the pastille format removes the chopping step, the cocoa-butter ratio is calibrated for melting, and the flavour range — 29% to 85%, with distinct profiles at each percentage — gives a baker actual decisions to make rather than just dark, milk, or white. The Ghana 80% is the pick for rich, assertive chocolate baking; the Guanaja 70% is the more practical choice because it's easier to find at retail. The white chocolate question usually ends at Dulcey. Valrhona's 32% blonde chocolate has a biscuity, caramelised character that sets it apart from the flat sweetness of standard white chocolate. If you're making ganaches, frostings, or anything where white chocolate is the flavour and not just sweetness, this is the one. For high-volume home baking — enriched doughs, breakfast cakes, anything where you're folding chips into batter rather than melting a large quantity — Islands' micro buttons are the practical answer. The 2kg format is a commitment, but the 75% dark and 55% milk buttons are sized for inclusion rather than chunks, which means even distribution without manual chopping. This is the format that makes the difference between a brioche with chocolate pockets and a brioche with chocolate boulders. Pierre Marcolini's cooking range is the newest entry and the most interesting one for the quality-conscious home baker. The range runs 45% to 82%, comes in button form, and sits at the craft end of the market — close enough to eat out of hand as a snack (the author mixes them with salted popcorn), which is a reasonable quality test in itself. A cooking chocolate you'd eat straight is a cooking chocolate worth baking with. The honest caveat is cost. Using £40 of craft chocolate in a batch of cookies is not madness if you are a Chocolate Correspondent with surplus stock; it is madness for everyone else. The practical hierarchy is: Valrhona Guanaja for most serious baking (widely available, professional-grade), Islands buttons for high-volume inclusion work (the 2kg bag normalises the price), and Marcolini when you want the craft-chocolate flavour profile without sourcing a specialist chocolate bar and breaking it up yourself. All three solve the same problem the same way — buttons or pastilles instead of bars — and all three justify the premium over supermarket own-label.
