Anchoa Crujiente: la Técnica del Restaurante con Tempura en Casa

Crispy Anchovy: The Restaurant Technique for Tempura at Home

May 26, 2026Maria José Sáez Pastor⏱ 3 min de lectura

In short: Premium Cantabrian anchovy in Japanese tempura: the fusion technique used by chefs like Aduriz. Batter with ice water + flour, fry for 90 seconds at 180°C, serve immediately. Size 0 or 00 is mandatory. Result: crispy anchovy on the outside, intense on the inside.

The concept: anchovy + Japanese tempura

Premium Cantabrian anchovy contains concentrated umami (480 mg free glutamate/100g). Combined with Japanese tempura (light batter + short frying at high temperature), it produces a bite where the crispy exterior contrasts with the deep interior flavor.

It's a Spanish-Japanese fusion technique that appears on the menus of avant-garde chefs like Aduriz, Berasategui, and Quique Dacosta. Surprisingly easy to reproduce at home with premium product.

Ingredients (4 people as a tapa)

  • 16 Cantabrian anchovies size 0 or 00 (4 per person)
  • 100g Japanese tempura flour (available at Mercadona oriental, large Carrefour, Amazon)
  • 150 ml VERY cold water (with ice cubes)
  • 500 ml high oleic sunflower oil or mild olive oil
  • Maldon salt
  • Lemon cut into quarters for serving
  • Optional: wasabi-mayonnaise sauce for dipping

Step-by-step (15 min total)

  1. Drain anchovies: remove anchovies from oil, pat dry lightly with kitchen paper (keep some oil for flavor).
  2. Prepare tempura batter: in a medium bowl, MIX flour + ice water with a whisk just enough to combine. The batter should have visible LUMPS (this creates the characteristic crispiness).
  3. Heat oil to 180°C (no more). Test with a small piece of batter: it should bubble and rise to the surface in 5 seconds.
  4. Dip each anchovy in tempura batter just before frying. DO NOT let it sit — the temperature of the ice water is what creates the crispiness, it should go directly into the hot oil.
  5. Fry for 90 seconds at 180°C until the tempura is lightly golden. No longer: the anchovy would cook and lose its character.
  6. Drain on kitchen paper and serve immediately with Maldon salt + lemon.

Common mistakes to avoid

1. Lukewarm instead of ice water: without the thermal shock, the tempura will be dense and oily. VERY cold water is ABSOLUTELY essential.

2. Overmixing the batter: complete integration eliminates the lumps that give crispiness. Mix only just enough, leave the lumps visible.

3. Cold oil: at <170°C, the batter absorbs oil and becomes greasy. Exactly 180°C.

4. Frying too long: >2 minutes cooks the anchovy internally, losing its raw umami character. 90 seconds maximum.

5. Letting the batter rest: it must go into the oil immediately. If you wait more than 30 seconds, the batter loses its crispy effect.

Frequently asked questions

Anchovy size 0 or size 00 for tempura?
Size 0 (medium fillets) is optimal. 00 (larger) can be too intense in the bite. Size 1 (smaller) disintegrates during handling. The standard choice: size 0 from Santoña or premium Cantabrian.
Can I make tempura without special Japanese flour?
Yes, alternative: 80g wheat flour + 20g cornstarch + pinch of sugar + ice water. It's NOT identical (tempura flour has a special starch/protein ratio) but gives a close result (85% similar).
And pairing?
Very cold brut nature cava (classic). Young Albariño Rías Baixas. Very cold pilsner beer. Premium sake if you want a Japanese connection. NO red wines.
Can it be prepared in advance?
NO. Tempura LOSES crispiness in 5-10 minutes. Eat within 2 minutes of frying. That's why it's a "show" dish in restaurants (fried on the spot). At home: have batter and oil ready, fry when guests arrive.
Sauce for dipping?
Wasabi-mayonnaise sauce: mayonnaise + 1 teaspoon of wasabi paste. Ponzu sauce (citrus + soy). Or simply fresh lemon + Maldon salt. Basque-Japanese chefs prefer the minimalist option (lemon + salt).
Why do premium restaurants offer this dish?
Because of the combination of theatricality (visible frying in an open kitchen) + high product quality (premium Cantabrian anchovy) + Japanese technique that enhances the perception of "haute cuisine." Real cost: low (€4 per person). Menu cost: €12-€18. High margin.

To conclude

Anchovy tempura is a simple dish that looks sophisticated. Once you master the technique (ice water + 180°C + 90 seconds), you'll have an appetizer in your repertoire that impresses guests without spending €25 per person in a restaurant. Cantabrian anchovy size 0 is the raw material — the rest is careful execution of 5 steps.
