To get to the bottom of this terrible Hellmann's mayonnaise rumor, I called Hellmann's Consumer Services this morning. (The number's on the side of the mayo, how handy!) I spoke with a very nice woman who told me there was a "slight modification in the formula in March." But she stressed that it wasn't a significant change and that it shouldn't be noticeable. I asked how often such modifications are done, and she said not too often, about every couple of years, they'll make a minor change. So faithful readers and Hellmann's eaters, it's time for a taste test. Can you tell the difference? I don't want to call for a boycott yet, or start a movement to get the anything changed back, if it's only a minor flavor tweak. But my husband swears he can taste the difference. Can you?
