Lawson's brownie recipe in How to Be a Domestic Goddess established a specific technical position: the correct brownie is deliberately underbaked to produce a fudgy, dense interior that is almost molten at the centre while the exterior is set. This is not carelessness — it is a precise target that requires understanding what temperature produces the desired texture.
A chocolate brownie baked to a specific internal state — the exterior set and beginning to pull from the pan edges, the interior still moist and fudgy rather than cakey. The doneness test is tactile rather than visual.
- The correct chocolate percentage: high-quality dark chocolate (minimum 70% cocoa) provides bitterness that balances the sugar and produces the complex chocolate character that milk chocolate cannot [VERIFY percentage] - Butter-to-chocolate ratio: equal weights produces the richest, most fudgy result. A higher flour ratio produces a cakey brownie that is a different and inferior product for this specific application [VERIFY ratio] - The underbaking target: the brownie is done when the edges are set (spring back slightly when pressed), the top has a thin, shiny crust, but the centre still wobbles when the pan is shaken — approximately 10°C below full doneness [VERIFY temperature: approximately 90°C internal vs 100°C fully baked] - Cool completely in the pan before cutting — cutting a warm underbaked brownie produces structural collapse. The fudgy interior sets further during cooling [VERIFY cooling time] - Line the pan with overhanging parchment — the overhang acts as handles for lifting the completely cooled brownie slab before cutting Decisive moment: The shaking test — at the minimum baking time, shake the pan gently. The edges should hold still; the centre should have a slight, liquid wobble. Remove at this moment. Overbaked brownies cannot be rescued; underbaked brownies will set to perfection as they cool.
