Technically 3 units for 0.75kg is correct. But your model is wrong because you forgot to introduce a additional block for each model to account for the food cooked.

Oh ok...But,why do we have to introduce an additional block when an equal mass(block) are cooked...Wasn't we supposed to remove a block each for both bar?..I don't get it..
