This combination mixed with sour cream also makes a fantastic dip!

tasting store bought horseradish and reflecting how mild it is, how is it that (imitation) wasabi which is also made up of horseradish is so pungent.

Store bought horseradish cream contains less than 10% horseradish (this may vary) and contains vegetable oil, milk, etc which would tone down the bite. As real wasabi is expensive a lot of wasabi paste is boosted with mustard seed flour. This may also help explain the variation.

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.
