Amazon カスタマー 5 I love knowing to the tenth of a degree what my milk is doing while cheesemaking. This device lets me heat the milk directly on a gas burner (while stirring, of course) and guestimate the increases in temperate as I get closer to the target. I heat fairly aggressively for the first 90% then slow the flame right down to "inch" my way to the final temperature. That way, I don't have to worry about overshoot. Although digital, the device doesn't seem to be bothered by steam coming off the milk. One nice feature is that you can quickly switch from C->F, so that depending on the recipe, I don't need to do any conversions.
