For the beef fillet tataki

Method
To make the ponzu sauce, mix together the soy sauce, rice vinegar and lemon juice, stirring until well combined. Weigh out 35g/1¼oz into a bowl for the salsa, reserving the rest for serving.
To make the onion ponzu salsa, combine the ponzu sauce with the onion and garlic purée and mix well. Slowly whisk in the grapeseed oil, then chill until required.
To make the garlic crisps, use a mandoline to finely slice the garlic into thin pieces and place them into a saucepan.
Cover with the milk and bring to the boil, then immediately remove from the heat.
Drain the garlic and rinse gently in cold running water, patting dry on a piece of kitchen paper.
Heat the vegetable oil in a small saucepan until it reaches 140C, then fry the garlic slices in small batches until they are golden brown. (CAUTION: hot oil can be dangerous. Do not leave unattended.) Drain well on kitchen paper and keep in a warm place until required.
To make the beef fillet tataki, place a cast iron pan over a high heat and allow to heat up until almost smoking.
Meanwhile, generously season the beef fillet all over with salt and pepper.
Drizzle over a small amount of grapeseed oil, then place the fillet into the hot pan to sear on all sides.
Once the fillet has colour on the outside but is still very rare quickly remove it from the pan. Place on a sheet of kitchen paper to rest.
To serve, thinly slice the fillet into even pieces and arrange across a deep plate or dish. Spoon a line of the onion ponzu salsa across the beef slices and top with a row of sliced spring onion. Drizzle over a little of the leftover ponzu sauce and garnish with the garlic crisps.
