In the past I've bored everyone I know and anyone unfortunate enough to stumble across this blog by wittering on about how undervalued I think gooseberries are these days. They make very fine jam and puddings, of course, but they're possibly even better in savoury dishes. So I can't let the gooseberry season pass without one more savoury recipe and this year it's a ketchup. Very easy and very delicious I promise. The weather hasn't been perfect this spring or summer so far (I'm a master of understatement) but the gooseberries finally arrived in abundance at the local pick-your-own farm. I really love a PYO and I'm not ashamed to say it.
I've combined the sharp gooseberries with the sweetness of beetroot and I suppose I should suggest that you pick fresh beetroot and cook your own. That's a very good thing to do but vacuum-packed, cooked beetroot without added vinegar will definitely do the job if you're pushed for time (and I bet you are).
Gooseberries are traditionally used alongside fish and this ketchup would work very well with fish burgers or fish cakes, but it's much more versatile than that. In particular, it's very fine with a classic beef burger. You could probably live without my recommendation but I'd say a burger made from the luxurious Wagyu beef produced by Ifor Humphreys in Powys and served in a freshly-baked brioche bun would be just about as good as it gets for me.
This will make roughly 400 - 500 ml of ketchup but it's difficult to be exact because much will depend on the juiciness of your gooseberries and just how thick you like your ketchup. Although the amounts given here worked for me, it's a forgiving recipe and you can change the spices to suit your taste. I won't be cross if you do.
1 onion, finely chopped
2 cloves garlic, very finely chopped
½ chilli (or more if you like some heat), deseeded and finely chopped
1 cm ginger (or thereabouts), peeled and grated
500 g gooseberries
100 ml cider (or white wine) vinegar
¼ tsp salt
A generous few turns of pepper
125 g granulated sugar
1 tsp English mustard powder
175 g cooked beetroot
Put all the ingredients in a non-reactive pan, place on a gentle heat and bring to the boil, stirring frequently. Simmer over a gentle heat for 30 minutes or so until all the ingredients are very tender.
Liquidise and then sieve the mixture. Taste and adjust the seasoning and the sweet/sour (vinegar/sugar) balance if it needs it. Hopefully the consistency will be to your liking but if it's too thin then return it to the cleaned pan and reduce it over a medium heat until you get the thickness you prefer. (It will thicken somewhat as it cools, so don't overdo it).
Cool a little and pour into sterilised bottles. This should keep for a few months in a cool, dark cupboard although I store it in the fridge just to be on the safe side and it should definitely be put in the fridge once opened.
