In NYT Connections, JAM, MESS, PICKLE, and FIX make up a category for Predicaments or difficult situations, and the four words can be used as synonyms of being in a bind. On the other hand, standard crosswords might give you clues to take these words as a "jam" (like traffic), a "mess" (a chaotic situation), a "pickle" (a tough spot), or pieces of food/preservation.
