Just like at Porto’s central Campanhã train station on Rua da Estação, O Astro Cervejaria Petisqueira on the other side of the street is reliably crowded every day. Its strategic location near the station helps account for that. But what really draws the crowds in is O Astro’s reputation as a must-stop for the definitive take on the bifana, one of Porto’s signature sandwiches. Much like the train station, O Astro brings locals and visitors together from all over Portugal, in search of one of Porto’s essential bites. At the most elemental level, the bifana is a pork sandwich, and in its most traditional form it includes thin slices of braised pork shank tucked into a crusty roll called a carcaça.

Some of my most powerful memories from 2020 are of the post-lockdown reunions with the owners of my favorite bodegas and grocery shops in Barcelona. After such a long period of confinement, it felt dizzying to move beyond the borders of my neighborhood and visit bars and restaurants again, which had newly reopened for takeaway. It was hard not to hug my friends – you know, we hug a lot in Spain. On one particularly ridiculous day in May, I remember sneaking a glass of vermut in a paper coffee cup at one of my local bodegas. The coffee cup was a disguise – any police patrolling the streets would think that I was just buying a takeaway coffee (permitted) and not having a drink inside a bar (forbidden).

Making chilaquiles always seemed a little out of my reach. I’m familiar with the dish’s humble beginnings, invented as a way of making use of day-old tortillas, but it still held some element of mystery for me: Under the practiced hands of locals, what seemed to be normal, everyday ingredients – fried tortillas, cooked salsa, raw onion, fresh cheese, double cream – transformed into a blend of flavors that felt impossible to recreate. This is a dish that I came to love after moving to Mexico City, where it quickly became my go-to when I sat down at a restaurant for breakfast. If I couldn’t find anyone to accompany me, I would often go out to breakfast alone just to eat chilaquiles.

When the first lockdown began in March 2020, one of the few things to disappear from supermarket shelves in Naples was yeast. Everyone was forced to stay home, where many got the idea to make pizza – baked, fried and stuffed. The result was that by mid-March, yeast was almost impossible to find. Fights broke out in grocery stores over packets of yeast. But I had my own secret reserves: Antonio ‘o fresellaro’s mother yeast. You see, on March 20 (at which point going out for food shopping was allowed), I escaped from home for a brief trip to buy Antonio Di Paolo’s freselle (twice-baked bread). While I was there, Antonio gifted me a piece of his family’s most precious treasure: their mother yeast.

For most of us around the globe, 2020 has been an unexpected and extremely challenging year. The world has never felt smaller. Here in Athens, we have been on a second strict lockdown for a month and a half now. My seven-year-old son is learning online, and I often feel like I’m juggling too many balls: coordinating and overseeing his schooling schedule, keeping the house as organized as I can considering that we spend almost all our time here, and trying to work at the same time. But the pandemic has had one positive effect, at least for me: I’ve found the time to experiment with recipes and spend quality time alone and focused (or at least semi-focused) in my kitchen. It has been keeping me sane, creative and positive. “My kitchen is my shrine and in it I shine!” is my motto for this weird year.

Homemade bread was a byproduct of the Covid-19 lockdown worldwide, as witnessed by the lack of flour on supermarket shelves and proudly displayed loaves on Instagram feeds. I understood the trend – bread gave people a sense of purpose, warmed homes with comforting scents and filled the void left by closed-down everything. Plus, the act of kneading gave the one-two punch of stress relief and tactile pleasure. Yet, I felt no need to knead. For I live in France, the land where boulangeries churn out 30 million baguettes a day. A place where bread is such an integral part of life that no meal is considered complete without it. Whatever I made at home wouldn’t match the loaves of someone who has devoted their life to the craft of bread making.

“Eat your greens,” they said. “Why not juice them?” Mexico asked. Since time immemorial, or at least for as long as I can remember, natural fruit and vegetable juices have been a thing in Mexico, long before juice bars became trendy in the rest of the world. The juguería (juice bar) is an essential part of the “stallscape” in every Mexican market. However, this tradition can trace its roots to Mexican households, where fresh juice and fruit-infused water have long been enjoyed during breakfast or lunch – and still are, although carbonated drinks are increasingly replacing them. Luckily, the juguerías continue to serve up dozens of juices with different flavors and purposes, from helping with a hangover effects to activating blood circulation and everything in between.

Editor’s note: Normally when December rolls around, we ask our correspondents to share their “Best Bites,” as a way to reflect on the year in eating. But 2020 was not a normal year. So at a time when the act of eating has changed for so many, our correspondents will write about their “Essential Bites,” the places, dishes, ingredients and other food-related items that were grounding and sustaining in this year of upheaval. Last March we loaded the car with our best cooking gear, bought enough provisions at Carrefour to fill a big red shopping cart, and headed to Garikula to ride out the pandemic in our village sanctuary. The seasonal cold winds ripped down the Tedzami Valley to shake winter off the trees; before unloading the car, we stoked the wood-burning stove to shake it out of our walls.
