this is not accurate but i think it's matter of timing and i reproduced this bug 6times for sure by following steps.
when selecting ingredient select(click) just 1~2 frame before animation process end. then after process end, cursor is 'grabbing' while actually not grabbing anything. then release (unsure must be on bowel or anywhere okay) and crush as normal. this is how make something from nothing- empty bowel, no ingredient consumed, additional output(1time/active). can be done sequently.
hope this information may be help.
