My girls & I love these. They have earned the nickname of "Mums Truffles" so that they know what to ask for:) I make two batches of these to use a whole packet of biscuits. I have also used different liqueurs to replace the sherry & essence, but mostly I use as written. I use Griffins "Super Wine" biscuits or "Girl Guide" biscuits in New Zealand. They are quick to make using a food processor. This recipe comes from my file of recipes by Alison Holst. NOTE: biscuits = cookies.
