Chapter 3 — The Sides
If you have ever ordered steak frites at a proper brasserie and wondered why their green beans eclipse anything you make at home, the secret is not a mystical ingredient—it is rigid culinary discipline. The beans undergo a rapid cuisson à l'anglaise in seawater-salty water, followed by a violent ice shock to lock in their structural integrity. The shallots are not carelessly sautéed; they are coaxed into a slow, sweet confit in high-fat cultured butter. Do not rush the shallots, and do not skimp on the butter. Put in the time, and yes, this is exactly what Spring Street tastes like.
Before you start
The beans can and ideally should be blanched and shocked up to a day in advance.
In a restaurant, this is done during morning prep. Wrap the thoroughly dried beans in paper towels, place them in a zip-top bag, and refrigerate overnight; bone-dry beans will accept the butter emulsion much better than wet ones.
Ingredients
- true haricots verts1 lb
- kosher salt2 tbsp
- traditional pink or grey shallots3 large
- premium cultured French butter3 tbsp
- neutral oil1 tbsp
- Champagne vinegar1 tbsp
- fleur de selto taste
- black pepperto taste
Method
- 01
Bring four quarts of water to a rolling, violent boil in a heavy Dutch oven and add the kosher salt.
The water should taste aggressively salty, like the sea. Set up a large bowl filled with equal parts ice and cold water nearby for the thermal shock.
- 02
Drop the beans into the boiling water and cook uncovered for exactly five to seven minutes.
You are looking for a croquante texture—tender and no longer tasting of raw starch, but still retaining a definitive snap. Keep the pot uncovered so volatile acids escape, preserving the vibrant green color.
- 03
Transfer the beans immediately from the boiling water into the ice bath and submerge them completely.
Use a spider skimmer or tongs. Let them sit for three to four minutes until they are entirely cold to the core, then drain and spread them on a clean kitchen towel to dry completely.
- 04
Melt the cultured butter and oil in a cast iron skillet over medium-low heat, then add the sliced shallots.
Toss the shallots to coat them in the fat, then practice patience. Allow them to slowly sweat and collapse for fifteen to twenty minutes until they become translucent, jammy, and pale golden brown without burning.
- 05
Increase the heat to medium-high and add the dry, blanched beans to the skillet.
Aggressively toss the beans with the confit shallots and butter for two to three minutes, merely reheating them and coating them in the lipid matrix rather than cooking them further.
- 06
Remove the skillet from the heat and drizzle the Champagne vinegar over the beans.
The acid will instantly deglaze any caramelized sugars stuck to the cast iron and emulsify with the butter to create a glossy sauce. Toss one final time, transfer to a warmed platter, and finish with a generous pinch of fleur de sel and black pepper.
Notes
The butter fat percentage is non-negotiable for the sauce.
Standard 80 percent American sweet cream butter has too much water, which will steam the beans and result in a flat flavor. You need 83 percent cultured butter to create the luxurious, tangy emulsion that carries the shallots.
