Takeaways
- đź Making custards requires harnessing the thickening power of eggs without scrambling them.
- đ„ Tempering eggs is essential to prevent curdling when adding them to a hot liquid.
- đ„ Egg proteins in a raw state are in tight bundles; heat causes them to unravel and form a firm texture.
- đĄ Overcooking leads to a tighter protein web, resulting in overcooked eggs and potential custard curdling.
- đ„Ł Tempering dilutes egg proteins, slowing their ability to bond and thus avoiding overcooking.
- đ©âđł Traditional tempering involves gradually adding hot liquid to whisked eggs while stirring.
- đ The blender method disperses egg proteins quickly, reducing the risk of curdling without the need for tempering.
- â± Some recipes require tempering if the liquid base needs preheating or infusion of flavors.
- đ You can skip tempering if the liquid base isn't preheated or infused, by whisking eggs directly into the cold liquid.
- đ Constant stirring and gentle heating are necessary when skipping the tempering step to ensure even cooking.
- đ The choice of whether to temper depends on the specific recipe requirements and the desired texture of the custard.
Q & A
What is the key ingredient in making custards like flan, ice cream, or creme anglaise?
-The key ingredient is eggs, which provide the thickening power needed for these custards.
Why is it important to avoid adding raw eggs directly to hot liquid?
-Adding raw eggs directly to hot liquid can cause them to scramble, which is not desirable in custard-based recipes.
What is the process of tempering eggs in cooking?
-Tempering eggs is the process of gradually diluting the egg proteins to prevent them from curdling when added to a hot liquid.
How do egg proteins behave when heat is applied?
-When heat is applied, the protein bundles in raw eggs start moving, unraveling, and eventually form an interconnected web, which gives cooked eggs a firm texture.
What happens if you overcook egg proteins?
-Overcooking causes the protein strands to come too close together, forming a tight web that can make a custard curdle and create an undesirable texture.
How does diluting egg proteins help prevent overcooking in a custard?
-Diluting egg proteins spreads them farther apart, slowing down their ability to bond with each other, thus preventing overcooking and curdling.
What is the traditional method of tempering eggs?
-The traditional method involves gradually adding some of the hot liquid to the whisked eggs in a thin stream while whisking continuously.
What is the blender method for tempering eggs, and what is its advantage?
-The blender method involves transferring the hot liquid to a blender and adding the eggs or blending the eggs into the liquid while running the blender on low. The advantage is that the blender's speed quickly disperses the proteins, reducing the risk of curdling.
When is tempering required in custard recipes?
-Tempering is required when the liquid base of the recipe needs to be preheated or infused with aromatics or spices before adding eggs.
Can you skip the tempering step in some situations?
-Yes, if the liquid base isn't being infused or preheated, you can skip the tempering step by whisking the cold cream or other liquid with the eggs and then gently heating them together.
What is the one-pot method for making custard without tempering, and what is required for this method?
-The one-pot method involves whisking the cold cream or other liquid with the eggs to sufficiently dilute them and then gently heating them together until thickened. This method requires constant stirring and scraping.

đź The Art of Egg Tempering in Custard Making
This paragraph discusses the crucial technique of tempering eggs when making custard-based dishes such as flan, ice cream, or creme anglaise. It explains that adding more eggs to a dish increases its thickness but also risks scrambling them if not done correctly. The paragraph delves into the science behind egg proteins, describing how they unravel and bond when heated, leading to a firm texture. It emphasizes the importance of tempering to prevent curdling and overcooking, which can spoil the texture of the custard. The traditional method of tempering involves whisking eggs gradually with a hot liquid, while an alternative method using a blender ensures quick dispersion of proteins to prevent curdling. The paragraph also touches on when tempering is necessary, such as when preheating a liquid base infused with aromatics or spices, and when it can be skipped for a simpler, one-pot approach.

Highlights
The key to making custard is harnessing the thickening power of eggs.
Adding more eggs results in a thicker custard.
Tempering eggs is essential to prevent them from scrambling when added to hot liquid.
Egg proteins in a raw state are in tight bundles that unravel with heat, causing them to bond and create a firm texture.
Overcooked eggs can make a custard curdle and eat.
Diluting egg proteins first slows down their ability to bond with each other.
Gentle and even heat is crucial to prevent eggs from overcooking during the tempering process.
Traditional tempering method involves gradually adding hot liquid to whisked eggs.
The blender method disperses egg proteins quickly, reducing the risk of curdling.
When to temper eggs depends on whether the liquid base needs preheating or infusion with aromatics.
Tempering is required if the liquid base of the recipe is preheated or infused with flavors.
Skipping the tempering step is possible if the liquid base doesn't need preheating or infusion.
Whisking cold cream or other liquid with eggs before gentle heating is a one-pot method to skip tempering.
The choice between tempering methods ultimately depends on the specific recipe requirements.

let's say you want to make a custard
whether for flan ice cream or a classic
sauce like creme anglaise
the key to each of those is to harness
the thickening power of eggs more eggs
you add the thicker the custard will be
but how do you add the eggs without
accidentally scrambling them in the
process the answer is often tempering
tempering eggs is the process of folks
diluting the egg protein and gradually
eating them to prevent them from
curdling when added to a hot liquid if
you had eggs straight into hot liquid
they scramble why let's take a closer
look at egg proteins when an egg is raw
the proteins are in tight bundles
floating in a liquid as heat is applied
those bundles start moving around and
bumping into each other until eventually
protein bundles unravel stretching their
strands throughout a solution and
hooking up with each other to form an
interconnected web that's what gives
cooked eggs a more firm texture if you
continue to apply each protein strands
will look closer and closer together
forming a tighter and tighter web too
tight and you end up with overcooked
eggs that can make a custard curdle and
eat so we can avoid an overcooked egg
sauce or broken custard by diluting the
egg proteins first this spreads them
farther apart slowing down their ability
to bond with each other as the heat
rises meanwhile applying gentle and even
heat ensures that they don't
accidentally overcook in the process
tempering the eggs is one of the main
techniques to accomplish this but you
don't always need to do it here are two
ways to temper and how to know when and
how to skip it for the traditional
method first set up a stable base for
your bowl allowing you to whisk with
and without the bowls spinning away
gradually add some of the hot liquid to
the whisk eggs by slowly pouring in a
thin stream and whisking as you go
combines the now diluted eggs back into
the pot and gently cook while stirring
until thickened this is a fast method
but it could go wrong if the hot liquid
is added too quickly for the blender
method transfer the hot liquid to a
blender and while running on low add the
eggs or blend the eggs into the liquid
using an immersion blender the blender
speed quickly disperses the proteins
before they can curdle and seiza
there's no real risk of currently thanks
to the power of the blender but now you
got to watch that blender when do you
know you need to temper these days most
custard and similar recipes are
automatically written with a tempering
step if you have to preheat the liquid
base of your recipe say your infusing
cream with aromatics or spices then
tempering is required so the eggs will
be combined with a hot liquid the truth
is you can choose to skip it in some
situations if the liquid base isn't
getting infused it doesn't need to
preheat before adding eggs you can skip
the tempering step this method requires
constant stirring and scraping but it's
one pot and no fuss
just whisk together the cold cream or
other liquid with the eggs to
sufficiently dilute them and then gently
heat them together until the eggs
unleash their dignity our in the end the
choice is yours
