This Clam Chowder is loaded with minced clams.
Add the onion, celery, carrots and potatoes to the clam juice. Place over medium heat and cook until all vegetables are softened.
Melt the butter in a 4 - 6 quart soup pot over medium high heat.
Stir flour into the butter with a large spoon and stir until well combined.
Continue cooking while flour bubbles up, then subsides to become looser and thinner. (This is a roux.)
Do not let the roux brown.
Pour one cup of the Half and Half into the roux, whisking to ensure the mixture does not clump up. Add the rest of the Half and Half and the milk, cup by cup, whisking thoroughly with each addition.
You should finish with a smooth milky mixture. If not, don't panic! You can run the base through a sieve, use an immersion mixer, or place it in a blender to get it smooth. (Be careful if you choose to use a blender, that you don't over fill it with the hot mixture. Better to do a few cups at a time!)
Stir in the white wine and red wine vinegar, salt, pepper and hot sauce.
Adjust seasonings to taste, if necessary.
