Hello there!
Any recommendations for a sous vide thermoplongeur, like this one? It should be available in Europe, temperature from 30 - 60°C (90 - 140°F) and have a cooking time of up to 36h. Its main purpose will be yogurt making.
I have an Anova, and I like it, but I wouldn’t consider it BIFL. After a few years, the manual controls are getting dodgy and it’s getting difficult to use without the app, which they’ve started charging for:
But I think you’re spot on with your other general recommendations.
