Passover product fails. Haddar mayonnaisse.
I bought a squeeze bottle of Haddar mayonnaisse. It visually looked fine in the bottle, but the moment it hit the matzah, it turned back into oil. A matzah sandwich isn't all that great to start with, but this was just disgusting. (a choice between a completely dry sandwich and one with oil dripping through the holes of the matzah. fortunately, i had ripe avocados ready to replace the stuff)
This was actually worse than the Manischevitz breakfast/energy bars I bought a number of years ago that tasted like bubble gum.
Not sure what brands I've bought before, but I'll avoid Haddar in the future.
Well, not a commercial product, but my local butcher, whose cooke take-out food is usually fine (not great, but good enough in a pinch), was selling fried eggplant slices.
I bought them, thinking I'd make moussaka or eggplant parmesan or something, and save myself a step.
I don't know what they used for the breading - as I think about it, it was probably potato starch, not matzoh meal, because it was very pale. But that wasn't the problem. I think it had to be the oil. Don't get me wrong - I'm sorry to admit that I'm a big fan of fried food, but this tasted just horrible, and the greasiness had a weird texture.
I threw it all out. Lesson learned.
