In Gujarat the winter menu is not a marketing exercise. Undhiyu, ponk and ubadiyu are available when the produce is available and not one week longer, and every kitchen in the state reorganises around that for about eight weeks.
The printed-menu problem
A seasonal list on a printed menu gives you three bad options: reprint twice a year, print an insert that gets lost, or leave the items on the menu all year and disappoint people for ten months.
Most kitchens choose the third, which is why so many menus carry an undhiyu that the kitchen will quietly talk you out of in April.
What a seasonal section should do
Three things, in order:
- Say when it runs. "December to February" under the section heading. Not "seasonal", which means nothing.
- Come off the menu when it ends. A hidden category, not a struck-through line.
- Come back with the same URL. The code on the table never changes, so the section returning is invisible to the diner except that it is suddenly there.
Sold out is different from out of season
These need different treatment and they are often conflated.
Sold out is a today problem — mark the item unavailable and leave it visible. The diner learns the kitchen is honest and orders something else.
Out of season is a months problem — hide the category. Leaving twelve struck-through items on a menu for ten months trains people to stop reading it.
The commercial argument
A limited run is worth more when it is visibly limited. A section that appears in November and disappears in February does the work that a "seasonal special" tag on a permanent menu never does, because the scarcity is real and the diner can see the calendar.
That only works if you actually remove it. The kitchens that keep undhiyu on the menu year-round have spent the scarcity and got nothing for it.
