Do not let the preparation time scare you away from the extraordinary recipe! Straining the yogurt is a great trick to create a thick base of the lemony, herbed cream spread. Set up the yogurt to strain overnight in the refrigerator and enjoy the easy assembly, done in under 20 minutes. The final pick-up appetizers are full of Greek-inspired zing. Each bite-sized round has a tantalizing combination of cool cucumber crunch, herbaceous yogurt cream and rich delightful shrimp. Make a double batch of the yogurt as these little bites will surely get lots of takers.
