I’ve ruined my share of meat by cutting in to check doneness. The MeatStick V Duo uses two wireless probes that you can put into two different cuts, and the app predicts when each will hit its target temperature. A small LCD base shows the temps so I don’t have to grab my phone with greasy hands. The probes can handle open flame up to 1200°F and are dishwasher safe. — MF

We switched from a pouring spout for our cooking oil to this dark glass bottle dispenser, which provides more accurate portions and helps preserve the oil’s freshness. The dispenser delivers a precise 1/4 teaspoon, or you can switch to spray mode to lightly coat your pans. I like to use the sprayer when cooking tortillas, because the fine mist of oil makes them crispy. — CD

This book, The Flavor Thesaurus; Pairings, recipes and ideas for the creative cook,  is original and without peers. It starts by mapping out 99 flavors of foods into a “flavor wheel,” and it then examines all the plausible combinations of these flavors, with comments on the pairing. I find it useful for cooking new things, but it is also a very enjoyable browse. How about trying these unexpected pairings: coconut & dill, or saffron & rhubarb, or walnut & cauliflower? There are thousands more, including well-loved common pairs. — KK
