上樣價錢 At the Upper Grade Price
只過三更後，就是辛酉，便開齋了。你明日殺生罷。如今且去安排些素的來，定照上樣價錢奉上。」只过三更后，就是辛酉，便开斋了。你明日杀生罢。如今且去安排些素的来，定照上样价钱奉上。」
逐句解 Line by line
Once the third watch is past it becomes xinyou, and the fast is broken.
辛酉 is the next day in the cycle, the fifty-eighth. 更 is gēng, a watch of the night, and the third of them is roughly midnight to two — so the fast ends in the small hours, not at dawn. Chinese days in this reckoning turn over at midnight, which is what makes the answer work.
Kill tomorrow, then.
罷 closes the line as ba, the particle that turns an order into a suggestion — not the bà that means to stop or finish.
For now go and get something plain made up — and we shall still pay at the upper-grade price."
素 is plain, meatless food, the standard word for it. 奉上 is to present respectfully, and it is the polite way of saying the money will be handed over. He has just promised her five mace a head for a vegetarian meal.
He has kept the price and cancelled the meat, which leaves her better off than before. That is why she takes it so well.
It is also the third time in one evening Pilgrim has promised money he does not have. The clothes were to be sent back, the innkeeper was to be paid in silver made from roof tile, and now the upper-grade price is guaranteed on a meal of beancurd.
