By now, Pokémon Café Remix has many gimmicks that are used in regular rotation in its puzzle stages - some certainly more than others. Each of those gimmicks in turn need to be dealt in certain ways in order to clear them, whether by linking Pokémon icons or using special icons (megaphones and skills). With so many gimmicks and only so many ways to clear them, it is potentially possible to have some that are very similar if not outright the same, and the latter case could be construed as giving "new flavors" to old gimmicks.
As an example, more recently there has been the addition of "bottle-type" gimmicks that if not cleared with a Pokémon that can handle them directly, they would generate other gimmicks. In one case, the soda pop creates soda bubbles if cleared by hitting it normally, and the mayo jar results in mayo when cleared in the same manner. Their mannerisms and usage of older gimmicks lend them their "new flavors".
Even more recently, chocolate cookies have been added, which require three hits for a normal clear. This is pretty much the same as the whipped cream, which is cleared in the same manner if not using a Pokémon with the specialty for it, or special icons. In fact, the appearance of the cookies is rather similar to whipped cream, only being chocolate-colored, which further suggests the "new flavor" aspect to the gimmick.
While new and old Pokémon alike can adapt to new gimmicks, the latter in particular through kitchen notes that are waited for them, it may be that it's hard to adapt new gimmicks in other ways that are different from the current gimmicks in their existing ways. Even so, whether that may or may not be necessary could depend on the puzzle stages and events to come, and in turn the implementations of the gimmicks.
Café Remix already has plenty of puzzle gimmicks to challenge old and new players alike, and they're still rather challenging in the puzzle stages where they are concerned. The next concern and challenge may then be having gimmicks that are nicely adapted to them, and it may be that in the process, some old gimmicks may just have some "new flavors".
