Keep the lychee fruit and syrup measures separate
Drain and measure the lychee fruit while retaining enough can syrup for its separate liquid amount. Do not treat half a cup of fruit sitting in syrup as both ingredients at once. Blend fruit, measured syrup and lime before straining into a stable jug; the sieve removes raspberry seeds while the mixture is still separate from ice and soda.
Divide the ice and strained fruit base evenly, then add the chilled soda slowly. Leave practical room for the drink above the ice and use a larger glass if needed. One gentle stir combines the drink before immediate serving. Keep extra canned fruit stored according to its package rather than returning handled garnish or strained leftovers to the untouched contents.
