I have tried many dishes from the book Dishes from Indonesia by Yohanni Johns and some are great others do not work at all. Just tried to cook the Rempeyek (Peanut Crackers) page 105 . Do not try this dish as it does not work. I believe it is the 2 cups of coconut milk that is the problem.
I believe you are best to check the recipes online first with youtube and so on.
I am married to an Indonesian and wanted to surprise him with this snack dish as too expensive to keep buying.
A total disaster. The batter disintegrates in the oil.
