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.

As regards horseradish, I have grown this plant, but in my opinion, it would be a mistake to think you can plant it in April and harvest in 24 weeks time and have a useful root. For Horseradish to get a nice thick root, with the distinct pungent flavour, it takes a good two years per plant. And do not underestimate how much work it is to clean the dirt out before shredding the root. It is a wonderful taste and worth the hard work, but in my experience, you need to set up a dedicated bed, plant the roots and then prepare to wait a few years to get the cycle of having a constant supply of usable nice thick roots. The roots grow very deep into the soil (a good 2-3+ feet) so it is a good idea to leave some room around each group of plants, because you need to dig quite a wide hole to get the roots out. We always harvest at Easter here in Sydney. Bon apetit.
