It’s fairly easy to deseed a mirliton. Slice the mirliton in half lengthwise right through the middle (there is usually a little trough on the larger end that helps identify the middle. The seed is an oblong, somewhat skinny white seed and you will probably slice it in two. Simply use a spoon to scoop out the seed from each half of the mirliton. For this recipe peel the mirliton first, then slice lengthwise. Some recipes don’t require the mirliton to be peeled, so just slice and scoop.
