Measuring
A Digital Scale
Buy one today. Nothing else in a kitchen improves consistency this much for the money, and volume measurement of flour is genuinely unreliable.

Measuring
The second thing to buy after a scale. Doneness is a temperature, and every other cue — colour, firmness, time — is an unreliable proxy for it.
Cutting
Buy one, learn to sharpen it, and skip the block set entirely. Sharpness matters far more than price above about the £40 mark.
Cookware
Worth owning if you sear, roast or bake often. Not the everyday pan people claim it is — it is slow to respond and genuinely heavy.
