Following on from my inspiration to pair rhubarb with fennel, I have been doing a few more experiments with rhubarb. I have lifted today’s idea almost wholesale from the Mister Kitchen rhubarb tasting menu. They served a sea bass with spinach and a rhubarb vinaigrette. It was great. Of course, I had to come home and fiddle about with it.
Rhubarb is most frequently eaten as dessert, and I am certainly partial to desserts and cakes with it in. People forget that it is actually a vegetable. It is seldom seen in savoury dishes, although I do know that a few bloggers have been experimenting with salads and as savoury compotes lately, so maybe there is a resurgence of rhubarb as a side dish in the offing. Who knows?
I certainly have a few more ideas that I want to try before my plant goes over this year, or I rest it in preparation for winter. Of course, once I am happy with each of the dishes, I will be sharing them here with you.
The version that I ate at Mr Kitchen had a mild olive oil, finely diced rhubarb and kalamata olives, with the stones pushed out, and the flesh torn into chunks. It was rustic and very simple. And it was delicious with the fish and the greens.
I spent quite a while messing about with various things, including shallots, herbs, black pepper, chillies, and so on. I have come to the conclusion that simple really is best. Shallots and rhubarb are both very astringent, so makes for a very sharp dressing, although that might be because I also acidulated the shallots in lemon juice first to take the rawness out of them. This combination as really an ingredient too far for me, so I ditched the shallots in favour of paring everything down
Raw rhubarb is crunchy and subtle. If you decide to follow my lead and make up a vinaigrette yourself, make sure whatever you use does not over power it. I stuck with very simple flavours for this vinaigrette – in fact it is a classic French dressing, with the addition of rhubarb. It works quite well with a pinch of chilli flakes, and with tarragon or chervil, instead of the mustard. I personally think that it is better with the more grassy olive oils, not the really punchy ones, but you may disagree.
Since there is nothing simpler than a vinaigrette, and rhubarb is at the peak of the season, I thought that I’d be a bot cheeky and have two entries to this month’s Simple and in Season, hosted by Ren Behan.
I do recommend that you give a rhubarb dressing a go. This one was lovely with salad and great with fish (I served it with tilapia fillet). I bet it would also be perfect with pork or chicken too.
What classic dressings do you know that might benefit from a little rhubarb?
Recipe: Rhubarb Vinaigrette
About 1/2 stalk very finely diced raw rhubarb
2-3 tbsp Grassy extra virgin olive oil
1 tsp Dijon mustard
Zest of half a lemon, pared
Lemon juice to taste
Once the rhubarb is prepared, Whisk together the mustard, zest and olive oil.
I used lemon with this dressing, because I wanted it to go with fish. You could also team the dressing with orange. Grapefruit works as well, although you will need much less than half the grapefruit zest. Which one you choose is entirely up to you, and you can change it to match your dish.
Add the rhubarb, and season. You will need to taste it at this stage. I found that adding a little lemon juice really lifted this into a great dressing, but the amount that you will need will depend on which citrus you are using, and how sharp your rhubarb is; which will vary with age, size and how long ago it was harvested.
Serve immediately if you can, on fish, a salad, or anything you like really. It does keep for a couple of days in the fridge, but it is better fresh, because the rhubarb will lose its crunch. So simple, there’s no excuse not to give this a go!
