Rhubarb jam by Bonne Maman

I first tasted rhubarb this summer at my homestay family's house and was pleased to find that Bonne Maman, a brand of jam available even in Japan, was offering three jars for the price of two at Carrefour a couple of weeks ago. In addition, as you can see from the photo, the bottle is offering 20% extra. What a deal (and what a treat it is).
In the back is my trusty toaster, two slices at a time.
