Dice the beetroot. Chop or grind the sunflower seeds very finely. One after the other, add the oil, lemon juice, vinegar and horseradish and mix well. Then season with salt and possibly Gomasio (sesame salt) as desired.
If you want it to be creamier, you can mix in a teaspoon of guar gum. Before adding it, you should mix it with 2 tablespoons of beetroot juice (or just some of the spread) so that there are no lumps.
