Grind the sesame seeds finely. A high-speed blender or spice grinder gives the best texture. Coarsely ground seeds can leave a gritty bite.
Don't overbake. Since this is a dense, fudgy-style cake, pull it from the oven as soon as a toothpick comes out mostly clean. A few minutes too long can dry it out. I speak from experience. While I experimented with this recipe, I baked it on several different settings and times. I found that the 25-minute mark on a gas stove results in a cake with the best crumb. Not dry nor too gooey.
Beat the eggs fully. The full 2 minutes of beating helps give the cake some lift, since there isn't a large amount of flour or leavening in this recipe.
Let the melted chocolate cool slightly before beating it into the egg mixture, so it doesn't scramble the eggs.
Use room-temperature eggs if possible, for a smoother batter.
