So, this is what we're doing? Okay.
I get 8 gold cheese and 6 gold goat cheese per day (14 total per day which 70 in 5 days; continuing: 98 per week, 392 per month), and I have a cellar packed to the brim with casks (not filled, I still have room to get to everything) so some of that is aged to iridium per month too, leaving me with 125 iridium goat cheese, 43 gold goat cheese and 224 gold cheese per month ...AND I have that many life elixirs just laying around.
So... what's next? Pull them out and measure? Come on.
And seriously, back to my cellar, cheese is worth too much to be eaten. It should be aged and sold. You want "better" health and energy restoration? Learn to cook and get some buffs too. Better food isn't defined by the HP and Energy restored, imho, it is the buffs. The HP/Energy restored is a small concern when you can bring a stack of 50. Every piece of cheese you eat is money down the drain imho.
My point was that having that many (51, or 17 per year, or just over 4 per season and thus about 1 purple mushroom per week) means that the rarity isn't as bad as folks make it out to be. That you can amass a significant enough quantity for use, not that it's the best thing ever, but it's the best thing you can get as soon as you've earned your first 5k, because you ain't getting that much milk that early.
I still think you miss the point entirely. The problem is reliability. Cheese has it, health elixirs from mushroom caves do not. When I'm diving mines, and I need health, I need it immediately, not next week. Also, your claim about 'you ain't getting that much milk that early' is... untrue. Basic barn with four cows down before the end of Spring is pretty typical for me. That's about four cheese per day starting, let's say first week of Summer since the cows have to grow up.
As far as cheese being 'too expensive to eat', it really isn't. I mean, sure, with Artisan (and who doesn't Artisan?) gold-star cheese goes for 482g/ea. Which, let's be fair, isn't bad, considering it's a daily production item. However, I consider it an investment in my infrastructure expansion, since it means avoiding the house upgrades entirely until you're done with your caving. However, if you're truly desperate to sell every last bit of cheese, you can just purchase Salads and have a reliable food source, assuming you run out of Salmonberries. They aren't quite as good, but they'll be a LOT more reliable than the health elixirs.
Here's the thing... once you've dived the mines and gotten enough Iridium for your needs... you never need to go into a dangerous area ever again, rendering food meaningless. Your boast about having just over 50 health elixirs by year 4? Falls kind of flat since I haven't gone underground since Year 1, except maybe some caving for copper and iron which, let's face it, are trivial at that point.
So the problem isn't just a lack of supply. The problem is that you quickly run out of demand for food. Once you have your sprinklers down, there's zero reason for food anymore. Which makes your stash of health elixirs basically a waste of space. Meanwhile, by going Bats instead of Mushrooms, I can get my Greenhouse unlocked sooner. And every week earlier I can get my greenhouse unlocked is a quarter million in my pocket. The number of health elixirs you can have in year four is meaningless since you'll never need them in year four. You only need food in your first year, maybe into your second at most. And you need something reliable and consistent, both things the health elixirs are not.
