Cut the avocados in half, remove the pit and scoop the flesh into the bowl of a food processor fitted with the steel blade.
Add the lime juice, sour cream, cream cheese and garlic and process until smooth.
Place in a bowl and season with salt.
Cover with plastic wrap, pressing wrap onto the surface of the dip.
Refrigerate at least 2 hours before serving, allowing the flavors to blend.
To serve, make a small well in the center of the dip and add salsa. Garnish with cilantro, if desired.
Unlike chunky guacamole that relies on hand-mashed textures, this blended dip achieves a completely uniform consistency through mechanical processing. Standard guacamole often breaks down quickly due to oxidation, but dairy fats added here alter that trajectory entirely.
The Processing Stage
Using a steel blade in a food processor breaks down raw garlic cloves much finer than manual mincing can achieve. Cream cheese and sour cream require softening at room temperature before blending to prevent solid lumps from forming in the mixture. Process the avocados, dairy, and lime juice continuously until the blades leave no visible green flecks.
Oxidative Control
Enzymatic browning occurs rapidly when polyphenol oxidase meets oxygen. Fresh lime juice lowers the pH level, which significantly slows this discoloration process. Pressing plastic wrap directly against the exposed surface eliminates air pockets during the mandatory two-hour refrigeration window.
Texture and Assembly
Adding salsa directly into the blended base creates watery streaks and muddy colors. Pouring salsa into a central well at service time keeps the contrasting red and green elements visually distinct. Coarsely snipped cilantro provides herbal brightness without overpowering the underlying allium notes from the garlic cloves.
