I want to know how to create a product that was common some decades ago. Ginger bread/cake with preserved ginger and no heat. Not just low, but none at all. And with a strong ginger flavour. Ginger flavour as entirely distinct from ginger heat. So, how can I make ginger cake with strong ginger taste and ginger pieces, but no heat?

I have tried going back to old recipe books, but nothing in there seems to make a difference - suggesting that it might even be the kind of ginger available. I did hear tell of soaking the ginger to remove the heat. But, when I tried it - it removed the flavor as well.


I give some context below - that is not strictly required for the question.

Some decades back, I liked gingerbread, chocolate ginger, and preserved ginger. Gingerbread had zero heat. My mother could bake it, her mother could bake it, I bought it frequently in the shops after I left home. I am thinking that, given the "weird suggestion" comments that it is a lost art. But, I hope that someone out there has the technique in their head.

Chocolate ginger and preserved ginger had a little heat. But over time I found that everything with ginger got hotter and hotter. Even ginger cake that I purchase today has heat. Ginger biscuits (the hard kind) have heat. And so on. I wonder how this can be avoided. I would like to bake ginger bread with strong ginger taste and no heat.

Yes, I did consider the possibility that my taste had changed. The totality of my experience on this precludes that conclusion. For example, I know that for some time I could hunt down preserved ginger without heat and I could tell the difference by looking at it.

The core problem here is that the pungency of ginger comes from the gingerol. If ginger is dried or mildly heated, then the gingerol is partially converted to shogaol, which is even more pungent. If it is heated to about 150 degrees Celsius, then the zingerone starts to dominate. Zingerone is not in fresh ginger (young or old) but is produced by cooking. It tastes more fruity and has no heat. Various sources suggest 150 degrees for several hours for the desired effect.
