I have a variable that I display on the screen of my app called {{data.}}.
In the example code:
<ion-item *ngFor="let cardapiohotrod of cardapiohotrod | async">{{cardapiohotrod.nome}}</ion-item>
Where it is written cardapiohotrod I would like to put the variable {{date.}}

Brother, ngFor serves to loop. in arrays for example, so it will take the positions of the array. More if you want to display the content if there is value in the variable. you can use: *ngIf or [Hidden]...etc
From what I see this variable is an array position already. in this case you could not loop it because it contains only one value.
