To get the hottest flavor when preparing horseradish root: DO NOT add vinegar while grinding the root! If you're using a food processor, add water, just enough to get it to grind well. Once it is fully ground, let it sit for about 5 minutes. THEN add vinegar. During the 5 minutes, the horseradish (once ground) undergoes a chemical reaction that makes it much stronger. The reaction is (I believe) with water, triggered by breaking up the cells. Vinegar stops this reaction; if you do it too early, the heat never develops. But after a few minutes, without vinegar, the heat will start to fade, so you add vinegar

Good advice about when to add the vinegar Mark, do you have preference i.e malt, cider, wine red or white or maybe balsamic? I've been to the USA but apart from temperate and sub tropical I don't know about the zones like yours which is 4a please enlighten.

Judy,, so here was I looking for a recipe (another dish) when I came across this one for horseradish sauce but alas no mayonnaise. Horseradish sauce - Traditional Ingredients. 4tb Grated Horseradish 1tb Caster Sugar 1ts Salt 2 ts Mustard, English 1/2sp Pepper 4tb Single cream A little malt vinegar can be added though this is not recommended. Mix all in a bowl and stir anti-clockwise, and just my suggestion is to substitute the cream for mayonnaise,and I suppose that with most recipes certain ingredients can be left out and others added such as my beetroot and horseradish sauce I add some red wine vinegar. Hope this helps.

Hi, I got my root stock from The Diggers Club. They carry all heritage seeds/roots/plants. I've been a member for years and have enjoyed great produce from their seeds.

My horseradish has been in a trough approx 60x30cm for years and never harvested, the new leaves are shooting. Can I repot or plant it in the ground now?
