The last few years I have made sure to invite my London friends to a proper Swedish crayfish party, as it’s my favourite non-holiday holiday in my native country. I usually buy the pre-cooked frozen crayfish from the Swedish shop but last year I actually found a crayfish seller who sold fresh crayfish caught in local lakes or ponds. The price was almost the same, and the quality so much better, but I also really wanted to cook my own crayfish!

Compared to lobsters who you usually cook in boiling water, we cook crayfish in a sort of brine that we then leave the crayfish in until we eat them, adding a salty dilly taste to the crustaceans.

My London friends love crayfish as much as I do, so I ordered 7 kg for 12 of us, which may sound like a lot, but we ate every single one. It was a little tricky cooking that many with not that many large pans to hand but I managed*, and had a good time in the process experimenting with two types of brine; one with just salt, sugar and dill and one with beer in (a common practice for cooking crayfish) that add more depth to the flavour.

Boiling crayfish, basic recipe

20 crayfish

2 1/2 litre water

75-100 ml salt

1 tsp sugar

plenty of dill flowers (dill seeds can be used instead)

Make sure all the crayfish are alive, discard any dead ones. Rinse in cold water. Bring water, salt, sugar and dill flowers to the boil. Put the crayfish in a colander and lower it into the boiling brine to cook the crayfish. Cook for 10 minutes, from the brine starts boiling again. Leave to cool in the brine, keep cold and eat within 24 hours. 

Boiling crayfish, with beer

20 crayfish

2 1/2 litre water

1 litre beer

75-100 ml salt

1 tsp sugar

plenty of dill flowers (dill seeds can be used instead)

Make sure all the crayfish are alive, discard any dead ones. Rinse in cold water. Bring water, beer, salt, sugar and dill flowers to the boil. Put the crayfish in a colander and lower it into the boiling brine to cook the crayfish. Cook for 10 minutes, from the brine starts boiling again. Leave to cool in the brine, keep cold and eat within 24 hours. 

*The trickiest part was actually storing 7 kgs of crayfish in its brine in a cold place. The fridge surely wasn’t large enough and it was full of all the other food we were having with the crayfish, so I put them in bowls and pans in the bath and filled it with ice. Bonus pic:
