Anova dominates the sales charts, but in many ways (raw heating power, looks, size, software quality), the Joule sous-vide circulator is actually the superior product, and Amazon’s running a rare $30 discount on it, today and tomorrow only.

The Joule White is actually a new model of the Joule, swapping the original’s stainless steel top and base with white plastic to match the rest of the unit. Otherwise, it’s exactly the same as the Joule White/Stainless, and will usually retail for $20 less at $179. Today’s launch sale though is a great chance to save even more.

If you don’t have any idea what the hell I’m talking about or why you might want to buy this, Lifehacker has a great sous-vide explainer here. Spoiler alert: It’s incredibly simple, and the results are fantastic.
