In a small saucepan, bring the half-and-half and nibs to a gentle boil over medium heat. Remove from heat, cover and let steep for 20 minutes.
Strain the half-and-half into a bowl, pressing on nibs to extract most of the liquid. Discard the nibs.
In a medium-heavy saucepan, mix the sugar, cornstarch and salt with about 1/3 cup of the infused half-and-half to form a smooth paste. Stir in the remaining half-and-half. Place over medium heat and stir constantly with a heatproof rubber spatula or wooden spoon until the mixture begins to thicken. Reduce the heat to low and continue stirring until the pudding begins to simmer. Simmer, stirring, for 1 more minute.
Remove from heat and pour into 6 (4- to 6-ounce) custard cups, Serve warm, cool or chilled.
