A sampling of the dishes served at the first night of the pop-up fundraiser

Update: Due to popular demand, the dinners have been extended one extra night — Wednesday, Jan. 15 is your last chance to join.

They were supposed to cook an exquisite feast at Reading Terminal Market this weekend. Billed as a Philadelphia version of Octavitas, it was to be an elegant take on the Puerto Rican celebration that extends the winter holidays longer than almost any other culture.

Then devastation hit the island, so famed chefs Cristina Martinez and Maria Mercedes Grubb turned their plan upside-down.

On Jan. 7, Puerto Rico withstood its biggest earthquake in a century, a 6.4-magnitude temblor that caused hundreds of evacuations and at least $110 million in damage, with more than 550 structures affected, according to PR Governor Wanda Vazquez. Over the past two weeks, the area has felt more than 1,200 tremors — many of them large, like the 5.9 quake that shook the ground along the island’s southern coast on Friday.

Instead of a fancy, ticketed dinner in the center of the city, the pair of Latina chefs, who were brought together by local nonprofit Gusto Philly, decided to collaborate on a series of pop-up fundraisers hosted in the intimate dining room at South Philly Barbacoa.

“Once we saw that this was so critical, that there was so much crisis,” Gusto cofounder Marangeli Mejia-Rabell told Billy Penn, “we decided to switch to something more casual, with more opportunities for people to take part and donate.”

Each night through Tuesday, Martinez — who has become renowned both for her cooking and her immigrant rights activism — will be joined at her famed taco restaurant by Grubb, one of Puerto Rico’s most admired and well-known restaurateurs.

After Grubb shops her way through the Italian Market, she’ll create a small menu of Philly-inflected Puerto Rican favorites, and serve the dishes at BYOB dinners to raise money for people affected by the quakes.

No reservations are required for these events, which start at 7 p.m. each evening and are seated on a first come, first served basis.

$500 raised on the first night, with more to come

The first pop-up took place Saturday night, and it was a huge success, Grubb said.

“We probably served 80 people — I ran out of food — but we raised over $500 in cash donations,” she told Billy Penn. “It was fabulous. Hopefully we’ll get to more today. People were so generous.”

The money, a combination of cash payments for the a la carte menu and donations that guests made directly via Venmo, will go to Serve PR, the nonprofit Grubb cofounded after Hurricane Maria to help people in the service industry get back on their feet.

“There’s no power in that area,” Grubb said, referring to the historic city of Ponce and the island’s southern coast, which she said is usually considered a vacation destination by residents of PR. “We want to help industry people that might be out of business at the minute. Give them generators, or carts for farmers’ markets, or help pay someone who hasn’t gotten a paycheck.”

The collaborative spirit is strong in Philadelphia, Grubb said, praising the city for its diverse restaurant culture.

“It’s not my first time visiting,” she said. “There’s a unique population here. I’m a huge fan of the food — the Vietnamese food, the cheesesteaks, the Italian food.”

And the tacos? “I landed at 11 in the morning [on Friday], and by 11:20 I had one of Cristina’s tacos in my hands. It met all the hype, and then some.”

After South Philly Barbacoa finishes its regular taco service on Sunday and Monday, plus Tuesday, when it’s usually closed, Grubb will turn the small dining room into a Puerto Rican restaurant.

Puerto Rican favorites made with Philadelphia ingredients

Each night’s menu will be slightly different, depending on what Grubb finds at the stands along 9th Street — “They had plantains! Amazing” — which will be combined with a few staples she brought from home:

  • Recao, also known as culantro
  • Fresh aji peppers
  • Gandules, aka pigeon peas

By way of example, check out Saturday’s menu:

Caldo Santo Vegano
parsnips, batata, yuca, coco
(a vegan version of the classic seafood and coconut soup)

Pastelon de Maduros
Kale, Ricotta, House Queso Fresco
(the sweet plantain lasagna has been Phily-ized with spinach and ricotta, Grubb said)

Carne Guisada
with carrots and rice
(rich beef stew)

Boricua Cassoulet
gandules, local Italian sausage, ham hock, recao
(a traditional casserole sparked with locally-prepared meats)

If you go, expect some of the same, and some new dishes too. “I’m thinking of making shrimp salad,” Grubb said on Sunday morning.

The dinners are BYO, but there’ll likely also be some complimentary sips from Don Q. The Ponce-headquartered spirits maker was going to be part of the original Octavia celebration at Reading Terminal, and eagerly donated to the pop-ups instead.

Tip from the organizers: if you want to assure yourself a seat, arrive between 7 and 8 p.m. If you want to just stop by to drop off a donation or say hello, you are welcome to do so, Grubb and Mejia-Rabell said.
