Interactive Tuna Tartare

For mother's day, we took mama to Cecconis for breakfast.  As we were leaving they rolled out a trolley with condiments for their tuna tartare.  I thought what a lovely idea for an appetizer at home:

chopped cornichons

chopped red chile

capers

chopped red onion (thin)

best EVOO

lemon/lime quarters

S&P

1. Bring large cutting board to table along with tray of condiments
2. Place slab of tuna on cutting board, chop for guests
3. Each guest helps him/herself to tuna and adds above condiments in any combo preferred (suggestion: red chile, onion, EVOO, lime, S&P)
