Cut tomato crosswise in half and squeeze out seeds and juice, then chop. Simmer tomato and cream in a small heavy saucepan over low heat until tomato is very soft (but not brown), about 10 minutes. Stir in Tabasco and sea salt.

Purée mixture with immersion blender until smooth. Force through a fine-mesh sieve into a small bowl. (If you have less than a scant 1/2 cup tomato purée, stir in hot water.) While still warm, whisk in gelatin.

Divide tomato mixture among molds (about 2 teaspoons each) and freeze until solid, at least 2 hours and up to 24. When frozen, unmold “yolks” and keep frozen in a sealed bag.

Put mozzarella, parmesan, and sea salt in a blender.

Sprinkle gelatin over cold milk in a very small saucepan and let soften 1 minute. Simmer over medium-low heat, stirring, until gelatin has dissolved, about 1 minute.

Pour hot milk mixture over cheese and blend until melted and smooth. Strain through a fine-mesh sieve into a measuring cup (you will have about 1 cup).

Spoon or pour the “whites” mixture into molds, filling them a little more than half full (about 2 tablespoons each). Add a frozen “yolk,” rounded side down, to each mold and press gently so that flat part of “yolk” is level with top of “white” to resemble a real hard-boiled egg half. Freeze until whites are solid, at least 2 hours and up to 24.
                                         
                                    
                                        - 
                                            
                                            
Unmold “eggs” and keep frozen in a sealed bag until ready to serve. Thaw “eggs” completely, then halve or quarter lengthwise before serving.
                                         
                                    
                                
                             
                        
                    
                    Cooks’ note: Unmolded “yolks” keep frozen 3 days.
