Leche de tigre clasica
In a Vitamix put flounder fillet, lime juice, fumet, celery, garlic, ice, salt and aji limo, and blend everything at a medium-low speed using the pulse button 4 times (we DON’T want fish paste). Once everything looks like it's been chopped in the blender, add the red onion hearts and cilantro, blend at a very short high-speed (pulse). By doing this we will have the aromas of the cilantro and onion but not the colour (green / purple). Strain it and keep the juice (leche de tigre). Store in the cooler in a plastic container, this has to be made every day before the shift, for the next day the flavour changes and the lime oxidises.
