If you’ve never sown Flower Sprouts, Kalettes, Brukale (all the same thing) before why not sow some this year.
They are a cross between Kale and Brussels Sprouts and are absolutely delicious. They are very easy to find now and are available from most of the large seed companies.
Why not give them a go this year, they are wonderful and in my opinion best sauteed for about 5 minutes with a little onion. When I have time I’ll make a video and show you.
