Any recipe I've seen has always suggested using homemade mayo within a week or so of making it, but the official Google answer for "How long does homemade mayo last in the fridge?" is 2 weeks. Hope that helps
@Lorna from Canada Wow, thank you so much for the thoughtful and thorough response! I'm definitely dedicated to giving this a go! I really want to do stuff like kale chips and other variations of vegetables because most backcountry meals have very, very few of those and I always crave them! I'd be curious to hear more about how you do the coleslaw vegetables! And I'm also going to try cauliflower rice!
Your comment about the Ramen kids made me laugh. Haha. Though I don't think I have to worry about that! I don't do National Parks (we have dogs and my babies aren't welcome in NPs) and we generally seek out less crowded spots so the dogs can enjoy offleash freedom! I'm pretty sure no one will be smelling our meals, let along ogling them! LOL.
I think @Jihanna answered everything you were asking about, but if there's something else, let us know.
I did want to say, you don't have to buy every single thing on the grocery list right away. You can meal plan some meals and just buy what you need for those meals, then add a new ingredient or two in a week or two. It is absolutely okay to keep things simple. Some people love coconut aminos, some don't think they're worth it, and you can definitely live without them. Even recipes that call for them aren't usually based on them, you're just adding some for flavor, and you can skip them and maybe add a little more salt or other seasonings.
You can end up spending a lot of money trying to buy everything, and then end up with stuff you don't use, so try to keep things simple at first.
