What analogy did Thomson use to explain the distribution of positive charge in his atomic model?

Thomson compared the distribution of positive charge in the atom to the red edible part of a watermelon, spread throughout the sphere.
Thomson used the analogy of a “plum pudding” or “raisin bun” to explain the distribution of positive charge in his atomic model, where the positively charged matrix resembled the dough and the electrons were the raisins.
