That was when Sabra turned to the other two, pointed down to the goop-covered rock and instructed them, "Taste it."

Totally matter-of-factly. Expectant, even, that at least one of them would see her command through. That one of the pair would actually go down into the crater, scoop some of the glowing, glue-like substance out with their hand, put it in their mouth and report back on the flavour in care-free manner.

"Taste it."

Because repeating the request clearly made it much more understandable, right?
