Spherification is a molecular gastronomy technique that transforms any liquid into delicate, liquid-filled caviar-like spheres using sodium alginate and calcium chloride baths. This foundational method creates elegant garnishes and flavor bursts for plated dishes.

Dissolve sodium alginate in 325g water using an immersion blender, blending for 5-10 minutes until fully dissolved.
In a pot, bring the sodium alginate solution to a boil over high heat, then remove from heat and let cool to room temperature.
In a separate bowl, dissolve 5g calcium chloride in 1000g (1 L) water.
In a small bowl, mix your liquid of choice with the sodium alginate solution at a roughly 2:3 v/v ratio (liquid of choice to sodium alginate solution).
Using a pipette or syringe, gently squeeze the liquid out drop by drop into the calcium chloride bath.
Let the spheres cook in the bath for about 1 minute.
Remove the spheres from the bath using a slotted spoon and rinse with water before serving.
Serve immediately. Note: you can continue to reuse the calcium chloride bath as you mix together portions of the sodium alginate bath with various different kinds of liquids.

Spheres are best consumed immediately or within 2-3 hours; store in a small amount of neutral liquid in the refrigerator, but membrane will continue to thicken over time.

Wine, fruit juices, broths, sauces, matcha, and flavored liqueurs all work well. Avoid high-alcohol spirits above 40% ABV as they interfere with gel formation.
Spheres can be made several hours in advance and kept in a small amount of their mother liquid in the refrigerator, but texture is best within 2-3 hours of creation.
This usually means the sodium alginate concentration is too low, the calcium bath is too weak, or the liquid has high acidity. Adjust ratios and test on small batches first.
A spherification spoon or small round spoon is essential for forming uniform spheres; a slotted spoon helps remove them from the baths.
30-60 seconds creates a thin gel membrane; 2-3 minutes creates a thicker shell. Timing depends on desired texture and membrane thickness.
