Vegetable Marrow or Gourd

Ingredients

Directions

Prepare

Gather the vegetable marrow when it is the size of an egg.
If the marrow is large and seedy, scoop out the seeds before cooking.

Cook the marrow

Boil it in salted water for 30 minutes or until tender.
Cut the cooked marrow into slices ½ inch thick.
Alternatively, cut the raw marrow into slices, scoop out the seeds, and fry in butter.

Serve

Lay the slices over buttered toast.
Sprinkle with pepper and salt, then pour melted butter over the top.
Serve the fried slices with melted butter and vinegar.
