Cold sauces & condiments
Marò (di fave)
Marò · Marò is a cold Ligurian pesto-sauce from the Riviera, traditionally made in a marble mortar by pounding fresh spring fava beans with garlic, fresh mint, aged sheep's-milk cheese and extra virgin olive oil. It is a bright, pale-green emulsified condiment — closer to Provençal pistou than to Genovese basil pesto in that nuts are not universal — and serves as a reusable base for pasta, bruschetta, and meat or fish accompaniments.
The formula
4 parts shelled favas : 1 part EVO oil by weight; garlic, mint, pecorino to taste
Classic Ponente ratio from Liguricettario: 300 g fresh shelled favas to 70 g oil ≈ 4.3:1 by weight. The traditional mortar recipe contains no vinegar; only a few modern or inland versions add drops of vinegar or lemon for acidity, and the cheese already provides tang.
Identity
- Cold, uncooked after pounding — member of the Ligurian pesti family
- Tradizionalmente pestato (pounded) in a marble mortar — never blended
- Spring preparation, because fresh favas are only seasonal in Italy
- Distinct from basil pesto: fresh mint is the signature herb, basil is absent
- Closest international cousin is Provençal pistou (nut-free) rather than Genovese pesto (basil + pine nuts)
- Regional split: Ponente uses Fiore Sardo and omits nuts; Levante adds pecorino AND pine nuts
Ingredients
| Base | Fresh fava (broad) beans, shelled and slipped from their bitter inner skin | Use very young, tender pods for sweetness; blanch 30–60 seconds and peel the outer skin if beans are mature. Frozen shelled favas are an acceptable off-season option (Cucina Ligure). |
| Fat | Ligurian extra virgin olive oil | Mild, fragrant oil; ~70 g per 300 g beans (4 tablespoons) is the classic dose. Streamed in slowly to emulsify. |
| Aromatics | Garlic (Vessalico if obtainable; otherwise ½–1 small clove per 300 g beans) | Vessalico is the Ligurian heritage variety prized for its mildness; ordinary garlic easily overpowers. |
| Aromatics | Fresh mint leaves | One tuft of leaves, torn by hand — provides the cool, characteristic top note and the signature color. |
| Enrichment | Aged sheep's-milk cheese — Fiore Sardo or Pecorino Brigasco | 30–40 g per 300 g beans. Liguricettario notes it 'balances the transudation of the favas' — it binds the watery purée and supplies salty, tangy counterpoint. |
| Seasoning | Coarse sea salt | Added by hand while pounding. Black pepper is optional and historically contested (Liguricettario's author dissents). |
| Acid | Vinegar or lemon juice (optional, modern variant only) | Not present in classic mortar recipes; a few contemporary or inland cooks add a few drops. Treat as a house variation, not a canonical ingredient. |
Method
- 1Shell fresh fava beans; if the beans are not tiny, blanch 30–60 seconds and slip off the bitter inner skinMature favas carry a bitter, fibrous seed coat; removing it gives the sweet flavor and pale-green color the sauce is named for.
- 2In a marble mortar, pound the favas to a coarse paste, working the pestle against the sides and rotating the mortar by its four handlesPounding — not blending — ruptures cells without aerating or heating, preserving the bright color and producing the dense, slightly textured body of an authentic marò.
- 3Add the garlic and torn mint leaves; continue pounding until fully incorporatedAdded after the first crush so the volatile mint and garlic oils aren't lost and the mint stays vivid green.
- 4Work in the grated Fiore Sardo or pecorinoThe aged sheep's-milk cheese binds the watery favas and supplies the saline, tangy counterpoint — without it the sauce weeps and tastes flat (Liguricettario).
- 5Stream in the olive oil slowly while still pounding, until the sauce emulsifies into a fluid, spoonable pasteSlow incorporation creates a stable emulsion so the oil doesn't separate on standing; the sauce should be looser than basil pesto so it can coat pasta.
- 6Adjust coarse salt (and pepper optionally), then leave the sauce a bit fluid; loosen with a few spoonfuls of warm pasta water at the moment of useFinal seasoning and dilution are done off the mortar so the sauce has the right cling and salinity for the dish it is finishing.
Techniques that matter
Mortar pounding (pestata)
Defining technique: a marble mortar with handles is rotated while the pestle works the sides, producing a dense paste without aerating the herbs or dulling the mint color.
Emulsification by streaming oil
Adding olive oil in a thin thread while pounding suspends fat droplets in the bean purée, yielding a glossy, stable sauce that does not split on standing.
Hot blanching of mature beans (sbollentatura)
A brief boil followed by a cold shock loosens the bitter seed coat so the inner cotyledon can be slipped free cleanly.
Variations & derivatives
Pestùn de basann-e (Ponente)Western Liguria — Imperia / San Remo area
Includes Fiore Sardo or Pecorino Brigasco and never adds nuts; pungent Vessalico garlic; mint-driven. Survives almost exclusively as a home/grandmother tradition.
Pesto di fave (Levante)Eastern Liguria — Riviera di Levante (Recco, Camogli, Portofino toward La Spezia)
More tourist-visible version; rounds the paste with pecorino AND pine nuts, and modern restaurants sometimes stir in cream for a 'creamy fava pesto' interpretation.
Salsa Marò with anchoviesInland Liguria
A few inland recipes stir in a salted anchovy or two once the paste is made; adds savoriness matched to grilled oily fish or boiled meats (Pesto & Pistou).
Off-season / frozen-fava versionModern household cooking
Cucina Ligure notes that frozen shelled favas (already peeled) can substitute for fresh; blanch briefly before proceeding as usual.
Used in these dishes
Substitutions
- Fresh fava beans → Frozen shelled fava beans (already peeled) — Drop straight from the freezer into boiling water for 1–2 minutes; flavor slightly flatter than peak-season fresh.
- Fresh fava beans → Dried peeled split favas, cooked until tender and drained — Available year-round; yields a more mealy, beige paste rather than the bright-green fresh version. Different flavor profile — not a 1:1 swap if color and freshness matter.changes result
- Vessalico garlic → Mild young spring garlic, or ½ a small clove of regular garlic — Vessalico is mild and almost sweet; standard garlic easily dominates.
- Fiore Sardo / Pecorino Brigasco → Aged Pecorino Romano (use sparingly), optionally with a little parmigiano — Romano is markedly saltier and sharper; reduce quantity or blend with parmigiano for balance.changes result
- Fresh mint → Fresh basil (in some modern 'pesto di fave') — Some contemporary recipes swap mint for basil; the result moves toward Genovese pesto and loses the cooling mint note.changes result
Troubleshooting
Sauce weeps and separates in the bowl
Beans were too watery and there isn't enough cheese/fat to bind → Work in another spoonful of grated pecorino and a thread of oil; serve promptly after mixing.
Bitter, 'green' off-flavor
The inner seed skins were not removed from mature beans → Use smaller/younger pods, or blanch and slip the skins off before pounding. There is no in-sauce fix once bitterness is in.
Color turns dull olive-brown quickly
Oxidation of chlorophyll from the mint and over-pounding or air exposure → Cover the surface with a thin film of olive oil, store in the fridge, and use within 24–48 hours; never blend at high speed.
Sauce too thick to coat pasta
Beans were very dry, or insufficient oil was streamed in during emulsification → Loosen with a few spoonfuls of starchy pasta cooking water just before tossing; do not add the water at the mortar stage.
