This was a recipe I developed for Blas y Tir, who produce beautiful tasting Leeks, Cauliflowers and Red Rudolph Potatoes down in Pembrokshire, Wales.

The caulfower is dressed in a flavoursome wholegrain mustard, turmeric and tomato dressing and the whole dish is roasted in vegetable stock.  By covering the tin with foil, it allows the vegetables to cook slowly without charring too quickly, giving ample time for all the strong flavours of the dressing, fresh rosemary and thyme to infuse.  It’s an absolutely delcious combination!

You can make this as a side dish or eat it as it is because it’s really rather filling with the cauliflower and potatoes.

It’s important to cut the potatoes into small cubes otherwise they will not cook within the time, so do not be tempted to cut them chunky like the cauliflower or you will need to cook for much longer!

This is a great ‘oven to table’ recipe which will fill your kitchen with incredible aromas, perfect for any table this Winter.
