I always save glass pickle jars, wash ‘em out, and use for storage in my pantry. And I have an assortment of large glass “cracker jars” (the square kind you find at Target or (gasp) Wal-Mart) for bulk items like flour, sugar, rice, etc.

Good, Accurate Thermometer. I favor the Thermoworks products—their thermopen is consistently well rated. Their accuracy and speed can’t be understated. And if you don’t think speed is relevant, watch how fast your caramel will turn into charcoal.

I’d say at least one good, high quality knife (and preferably a knife block). You don’t have to drop several hundred, but don’t go bargain basement. The difference over a cheap knife is actually pretty significant.

Mixing Bowls. I have a set similar to these, but with a few extra sizes. (and a few duplicates)

Measuring cups and spoons. Even if you’re not doing a lot of precise measuring, a good set of measuring cups can be quite useful. I have this set, as well as an extra half-cup one.
