Step 1

Combine lemon juice, ginger, turmeric, honey, water and pepper in a blender; process until smooth, 30 seconds to 1 minute.

Step 2

Strain the juice through a fine-mesh strainer into a large measuring cup, pressing solids with a spoon to extract juice; you should have about 1 cup of juice. Discard solids.

Step 3

Evenly pour the juice into a 9-ounce silicone ice cube tray. Freeze until solid, at least 1 hour.

Step 4

To make 1 serving: Bring 8 ounces water to a boil. Place 1 frozen cube in a mug or heatproof glass; add the hot water. Serve immediately.
