1/2 Celeriac, 2 potatoes, 2 tablespoons butter, salt.
I loathe celery. I feel the way about celery that Stewie does about broccoli. It tastes horrible, it has a horrible texture and I find it rather offensive that it takes more calories to eat it than it actually contains. Celeriac on the other hand, despite being somewhat celery flavoured is actually delicious raw in salads but my absolute favourite way to serve it is this wonderful, creamy, earthy mash.
1) Peel the celeriac root with a sharp knife and slice into chunks. Peel and slice the potato and boil in hot salted water for 20 minutes.
2) Strain and puree in a blender along with the butter and salt and serve.
