It’s a well-established part of my life that when I’m going out with a specific list of ingredients, something on that list will either be too exotic for the store I’m at or completely sold out on that day.
One time I needed butterscotch topping to try a butterbeer recipe and at the first grocery store, they just didn’t seem to carry any. Then I went to Safeway and stood in shock as I looked at the shelf of caramel toppings with one very empty row with a butterscotch tag underneath. Once I needed cilantro for guac and the store was out. Another time it was daikon.
This happened to me again on Superbowl Sunday.
