Halakhah for Menachot 154:9

And the content of those that came as matsa with the thanksgiving offering was like this: They would make thirty loaves from the ten issaron of flour. Ten of them were made by baking in the oven, meaning to say that nothing was done to them, except for putting an eighth of a log of oil into its dough, as such is a law of Moshe from Sinai. And ten of them are called rekikin (soaked in oil); but there is no difference between the ten that were soaked and the ten that were oven-baked, except that with the ten that were oven-baked, they would mix the eighth of a log of oil at the time of kneading, but with the soaked ones, they would smear the eighth of a log of oil after their being baked in the oven. And ten of them are called murbakhot (roasted in oil) - and the understanding of roasting is that they would scald the loaf in boiling water and bake it a little, and afterwards roast it in oil, in the way that people roast (fry) donuts in a pan. And it is roasted in the oil of the ten roasted ones, as the oil in which [each one] was roasted was a fourth of a log, [which when totaled] is the measure of all the oil of the [other] twenty loaves - and the measure of oil of the roasted ones is also a law of Moshe from Sinai. And that which we said is the understanding of murbakhot in every place in the Torah. And it is explained there (Menachot 77b), how much the share of the priest is in the loaves - and the rest is eaten by the owners. And the rest of all of its details are in Tractate Zevachim.
