I did that by pouring mostly white for the bar, and using brown batter in one squeeze bottle and gold in another. Squeeze the bottle pretty firmly to penetrate the white. and go back and forth down the length of the mold, saving a bit for the top to swirl with a skewer.I think it looks great
Give a week or so and it may all be all that color. Was that a mini drop swirl? I’m so bad at those haha.
I know, i really like that one lol.Wish there was some way to make a dark rind like that stay without discoloring the whole bar.
