> [@Little\_Nemo](#): > > It’s relatively easy to make. But if all you want is to make a tuna fish sandwich, do you really want to have to whip up a home-made batch of mayonnaise for it? I’m sure the sandwich would be better if I baked a fresh loaf of bread for it too but sometimes you just want quick convenience. Totally see your point, but then again, maybe fresh baked bread and homemade mayonnaise _should_ be the ideal way to go, especially if your tuna is sashimi grade ahi. /foodie ---

Yeah but who really wants to wait the four to five years for the pepper plants to grow and mature in the garden waiting for the peppercorns.

I buy the Costco sized mayo in November because a lot of my appetizers call for mayo and I know I’ll use it up in no time. Otherwise, I prefer the smaller jars. And while I won’t eat bottled salad dressing (homemade is the only way to go), I still use bottled mayo for sammies and appies. ---

> [@Quartz](#): > > Why bother? It’s easy to make it yourself. Egg yolk plus oil of your choice, a bit of mustard, pepper, and salt. Then add flavourings if required (mustard, garlic, etc). :rolleyes: Wait, you _buy_ eggs, oil, mustard, garlic, etc? It’s so much easier to grow them yourself. Well, you grow the plants that you harvest the oil from, but you know what I meant. And hand-mined salt is soooooo much easier and tastier than store-bought. ---

You raise _naturally-evolved_ tuna in your backyard? Pfft…I raise _genetically engineered_ tuna (toxin-free, non-fishy flavored and possessing a zipper along their ventral plane for easy gut-removal). I hire a wet nurse to breast feed each baby fry to adulthood. …and I only slaughter those tuna who have severe suicidal ideation, because killing happy tuna would be barbaric.
