Taste test time. Both of the below cooked and sampled with some roast pork.
Jury is out, as in neither were 'wow, must cook that again'. If anything a mixture of the two was the nicest. As in need to tweak.
One bit to tweak is the sage. I used purple sage leaves which is milder than green sage and could have done with a couple more leaves if I use purple sage leaves again
Rhubarb, ginger and sage sauce
Cut 400g rhubarb stalks into 2cm chunks (halve if thick stalks). Stew lightly in 20g butter with 2 finely chopped shallots, 2cm grated fresh ginger, 10 sage leaves chopped and some salt and pepper for 15 minutes. Increase heat to get desired consistency. Add honey to taste.
