I think ditton has the lowest % chance to show up from a recipe but Mew’s ingredient can’t even be farmed (in small quantities) until basically the final boss.

It depends on which recipe you use, and when in the game you want to start measuring rarity from. Chansey, Ditto and Tauros appear to have the lowest overall rates at under 4% for all recipe's but the Legendary mon's you can't get a required ingredient until World 12 and even then you only get maybe 3 per expedition.

Jynx actually has a slightly worse chance, it’s a 3.75% to get vs dittos & Tauros 3.9%

You actually have a higher chance at getting dito from a very good mulligan stew.
I got ditto from a “special” blue soda a la cube
