Honkai Star Rail: Recovery Secret Technique Point Food Acquisition Method
In the order shown in the picture, items 1, 3, 4, 5, and 6 are purchased. The store refreshes with a cooldown. Items 7, 8, 9, and 10 are made. Theoretically, if you have enough materials, there is no limit to the quantity you can make. Some foods may deduct health, but is that really a big deal?

In summary, highly recommend item 9, the Ingenious Snack, as materials are easily obtained.
Items 1, 3, 4, 5, and 6 are the next best options to buy. They are quickly acquired, but demand often exceeds supply due to store refresh cooldowns.
Items 7, 8, and 10 are the third recommendation. While they can be made, they require common junk materials which cannot be purchased and can only be obtained by destroying objects in Yaliluo. Also, there’s no telling when story missions might require a few, so you might end up hoeing the land.

Item 2 is the least recommended, as there seems to be no way to obtain it currently. Anyway, I’m not willing to use it.
The Rejuvenating Pill is in Chang Le Tian.
The Sweet Dream Syrup is in the Golden Moment.
The Dehydrated Emergency Light is in the Flowing Cloud Ferry.
The Fried Rock Crab and Gem Lizard Skewer are together in Pan Yan Town.

Energy Reception, Star Yam BoBo, and Punishment Food are made by yourself, with the following recipes.
Lastly, the truly magical Ingenious Snack!!!
The ingredients require two types, from three sources:
- The green one can be obtained as a byproduct from the Golden Flowers in Yaliluo, but you can only get the green ones. Who would spend stamina specifically to get them? Well, I wouldn’t.
- Commissions, my personal favorite way. Just click twice a day, and you’ll have both types of materials. It’s enough for players who don’t hoe the land.
- Buy directly from the Star Chart Hub, where both types of materials are available, but again, supply often falls short of demand.
