Prepare everything you need and weigh each ingredient before you begin, as you will not have time for hesitation. The mixture will set as you pour it into the mould.
I highly recommend a practice run before doubling the quantities for a larger batch.
Works with
xanthan gum (U.S. option
HERE) as well as
glucomannan (i.e. konjac) (U.S. option
HERE) but the best result is with guar gum.
The marshmallow will be springy and awkward to cut. The easiest way to do it is to create a shallow dent by sliding the tip of a wet knife across the top, then open the 'wound' with your fingers as you slice all the way down and across (keep the knife wet). I use
THESE very sharp ceramic knives (U.S. option
HERE).
Due to the minute quantities needed for this recipe, PRECISION SCALES are best. Click
