Unusual pairings
Pairs the library can cite that almost nobody makes.
- Caviar + Walnut
both carry 1-octen-3-ol, mushroom (56 of 341 carry it)
- Caviar + Oyster
both carry methional, cooked potato (17 of 341 carry it)
- Caviar + Kimchi
both carry diallyl sulfide, garlic (3 of 341 carry it)
Every one of its 28 compounds carries a paper the library can cite.
