Luckily peanut butter had reached Prague supermarket shelves by then. I tried them all: Lidl’s “Mcennedy American Way” which to me resembled the color of pantyhose and had a faint, inexplicable graininess, Tesco smooth and crunchy varieties, a more palatable texture but way too salty, and the gold standard to which I owe many excess pregnancy kilos: M&S Simply Peanut Butter Smooth.
