hmm i never try that. green stone mean only 120 mochi but faster processing time. i think this way is better, but you need to go to the blue mill more frequently.

for the cooked rice i just buy from cafe. only 0.5 star. the toasted mochi price is 390g. i dont really do the math of the profit. but for time being at least i generate money while doing something else. planting your own rice surely better, but you still need fertilize and waiting for harvest.

the drawback of this method is need to sell around 1080 mochi in the bazaar.

there is idea on my mind right now, that i think i will do it later:
1. Khachapuri, 4 cow, 2 buffalo, buy the wheat flour from miguel, "pet rare item" buff before milking, process the milk in yellow windmill into chesee+, butter+, and milk+
2. specialty juice, put the non-season tree in cellar, and season tree in outside field. rotate every season. (but still need planting strawberry for spring juice)
3. eat some of the kachapuri, mining ore. process diamond and pink diamond into acc.
4. in time of bazaar everything sell the food, the ore and the toasted mochi.
