Well, I found the recipe, though it wasn't in the book I thought contained
it. (It's actually in _Big Flavors of the Hot Sun_ by Christopher
Schlesinger.) The method I give above leaves out molasses and white vinegar,
which appear in the original recipe. That recipe also does *not* contain the
mustard seeds; that was a tweak I came up with the first time I made the
sambal (about 15 years ago), and I've kept it ever since because I like the
added flavor and texture the mustard seeds add.
