Straining is the step that turns a good sauce into a genuinely restaurant-smooth one — removing seeds, fiber, and small solids that a blender alone can’t fully break down. The strainer‘s mesh quality and frame determine how well that actually works in practice.

What Actually Matters
Mesh Fineness
Mesh density is usually described in terms like fine, extra-fine, or by a mesh count number. For genuinely silky sauces — a coulis, a refined tomato sauce, a citrus curd — you want the finest mesh you can find, since anything coarser will let through small seeds and fibrous bits.
Frame and Handle Sturdiness
Pushing a thick sauce through fine mesh with a spatula or ladle puts real pressure on the strainer’s frame. A flimsy frame flexes and distorts under that pressure, which both slows the process and can eventually deform the mesh itself.
Double-Layer or Reinforced Mesh
Fine mesh alone can be delicate and prone to denting or tearing with repeated hard use. Strainers with a reinforced or double-layer mesh hold up notably better over time to the pressure of forcing thick sauce through.
From My Kitchen: The Strainer That Bent Under Pressure
I once used a cheap, thin-framed fine mesh strainer to push a thick raspberry sauce through for a dessert, pressing fairly hard with the back of a spoon to force it through the fine mesh. The frame visibly bent under that pressure, and the mesh warped slightly, which afterward left the strainer sitting unevenly whenever I tried to rest it over a bowl. A sturdier, more solidly framed strainer handles that same pressure without deforming — worth paying attention to since fine mesh work inherently requires firmer pressure than straining something thin like stock.
Worth Considering
This set of three stainless steel fine mesh strainers covers a useful range of sizes for different batch quantities.
This small handled fine mesh strainer set is a good pick for smaller-batch sauces and precise straining tasks.
Mesh Count and What It Actually Catches
Mesh is measured in openings per inch, and the number tells you what a strainer is for. Around 40 to 60 is a general-purpose kitchen sieve — it drains pasta water and catches pips, but a sauce passed through it will still feel slightly textured. Between 80 and 100 is the range that matters for sauces, custards and purees, fine enough to hold back skins, fibres and any small lumps of thickener. Above 150 you are into tea straining and clarifying stock, where flow becomes slow enough to be impractical for a thick sauce.
Frame rigidity matters almost as much as mesh. A fine mesh under load flexes, and a flimsy rim lets the mesh bow away from the frame — which is how strainers develop a gap at the edge that quietly lets unstrained sauce through. A reinforced rim and a frame that does not deform when you press a ladle against it is the practical difference between a strainer that lasts a year and one that lasts ten.
Quick Comparison
| Mesh | Openings per inch | Best for |
|---|---|---|
| Coarse | 20–40 | Draining, rinsing, large solids |
| Medium | 40–60 | General sieving, dusting flour |
| Fine | 80–100 | Sauces, custards, purees, gravy |
| Very fine | 150+ | Tea, clarifying stock, sugar work |
Technique: Do Not Push, Tap
The instinct is to press the solids through with the back of a ladle, and it defeats the purpose — forcing fibre and skin through the mesh puts the exact material you were trying to remove back into your sauce. What works is gentler: ladle the sauce in, then move the ladle back and forth over the surface in a stirring motion so the liquid is drawn down without the solids being crushed. When flow slows, tap the rim of the strainer firmly against your hand or the bowl, which clears the underside where a skin of solids has formed.
The other habit worth building is straining while things are still warm. A cooled sauce is more viscous and passes through a fine mesh far more slowly, and a set custard will barely go through at all. Strain as soon as the sauce comes off the heat, then cool it in the bowl it was strained into.
Two Strainers Worth Considering
Best set: Three Stainless Steel Fine Mesh Strainers
Three sizes covers the actual range of jobs — a large one over a bowl for a pan of sauce, a medium for everyday sieving, and a small one for straining a single portion or dusting. Reinforced rims are the thing to check, and these hold their shape under a ladle.
Pros
- Three sizes cover most straining jobs
- Reinforced rims resist deforming
- Hook and handle for resting over bowls
Cons
- Large sizes take real drawer space
- Fine mesh needs immediate rinsing
Best for small jobs: Small Handled Fine Mesh Strainer Set
Small strainers get used constantly — straining a lemon, dusting icing sugar, catching seeds from a sauce, sieving a spoonful of flour. If you already own a large sieve, this is the gap worth filling rather than another big one.
Pros
- The size actually used most often
- Easy to store and quick to wash
- Fine enough for silky results on small batches
Cons
- Too small for a full pan of sauce
- Lighter frames than heavy-duty models
Frequently Asked Questions
What’s the difference between a fine mesh strainer and cheesecloth?
A fine mesh strainer is faster and reusable, while cheesecloth catches even finer particles but is slower and single-use. For most sauce work, a good fine mesh strainer alone is enough; cheesecloth is for when you need an especially clear, particle-free result.
Can I use the same strainer for stock and sauce straining?
You can, but a single fine mesh strainer is a compromise — very fine mesh strains sauces well but slows down large volumes of stock. If you do both often, having one coarser and one fine strainer is worth it.
How do I clean fine mesh without damaging it?
A soft brush rather than a scrubbing pad prevents stretching or tearing the mesh over time. Soaking briefly to loosen stuck bits before brushing also helps avoid needing to scrub hard.
Can I use cheesecloth instead of a fine mesh strainer?
For some jobs it is better — cheesecloth or a clean cotton cloth catches finer particles than any kitchen mesh and is what you want for clarifying stock or making a very smooth nut milk. It is slower, and it is awkward for a hot sauce you want to strain quickly. The practical approach is a fine mesh strainer for everyday sauces and a cloth laid inside it on the occasions where you want genuine clarity.
How do you clean fine mesh properly?
Rinse it from the outside in, under a strong stream of hot water, immediately after use — the solids are sitting on the inside surface, so pushing water through from the back lifts them out rather than driving them further into the mesh. Anything dried on needs a soak rather than scrubbing, since a stiff brush distorts fine mesh and creates the gaps that let sauce through unstrained.
