Tuna Shopping Tip

Seafood shopping is quite easy in the general sense. Rule of thumb: if it smells fishy, don't buy. Fresh seafood should smell mild and more like the ocean and sea water rather than fish.

Tuna Cooking Tip

Looking for a quick mid-week dinner? Seafood is a safe bet. It's quick to cook and simple recipes can get dinner on the table in 20 minutes.

Tuna Wine Pairing

Most white wines (especially albariño) and rosé with most fish dishes. Muscadet, sancerre, or New Zealand sauvignon blanc with cold fish dishes; chardonnay, pinot gris/grigio, or pinot blanc with grilled or roasted fish; sauvignon blanc or gewürztraminer with baked fish; grüner veltliner with fish pâté; vintage or non-vintage champagne or sparkling wine with light fish dishes; fino or manzanilla with small fried fish; junmai, junmai-ginjo, or junmai-daiginjo with teriyaki fish.
