English: “Aviv roasted in fire, crushed” — I do not know if the aviv is roasted or the crushed grain is roasted; when it says “in fire” it interrupts the matter.
Parsing of kalui vs geres — roasting attaches to the aviv stage, not to the crushed product.
The roasting attaches to the aviv stage, not to the crushed product. The intervening phrase “in fire” is read as interrupting the sequence so that the roasting is of the early grain itself, before it is crushed.
